Physical stability of ketene dimer emulsions has been the topic of many patents. For example, Edwards, et al. (U.S. Pat. No. 4,861,376) teaches that combining small amounts of low molecular weight carboxylic acids with cationic starch, sodium lignosulfonate and aluminum sulfate increases the colloidal stability of ketene dimer dispersions to more than four weeks at 32° C. Schmid, et al. (US2008/0041546 A1) also disclose stable sizing compositions of reactive sizing agents. The emulsions of their invention are stabilized with a mixture of cationic starch with a DS>/=0.05, anionic dispersant and a linear nitrogen-containing polymer. Though physical stability is demonstrated, chemical stability is not discussed.

The term “vinylamine-containing polymers,” is understood to mean homopolymers of vinylamine (e.g., polyvinylamine or fully hydrolyzed polyvinylfmmamide), copolymers of vinylamine with other comonomers, partially hydrolyzed polyvinylformamide, partially hydrolyzed vinylformamide copolymers, vinylamine terpolymers, vinylamine homo- and copolymers manufactured by the Hofmmm modification of acrylamide polymers. Examples of such polymers can be found in U.S. Pat. No. 6,159,340 to Niessner, et al.
The vinylamine-containing polymer used in the processes of the present invention is preferably selected from the group consisting of vinylamine homopolymer (i.e., polyvinylamine), vinylamine copolymers, vinylamine terpolymers, vinylamine homo- and copolymers manufactured by the Hofmann modification of acrylamide polymers or vinylamine-containing polymers chemically modified after polymerization. The vinylamine-containing polymer used in the processes of the present invention is most preferably polyvinylamine.
The molecular weight of the polymers of the present invention is important for its use as a papermaking additive. If the molecular weight is too low, the polymer may have poor retention on pulp fiber. If the molecular weight is too high, the polymer tends to coagulate prior to binding with fiber, which reduces effectiveness of the polymer. The molecular weight (Mw) of the vinylamine-containing polymers used to prepare the present invention is in the range of from 4,000; 10,000; 20,000; 50,000; 75,000; 100,000; 150,000; or 200,000 to 400,000; 450,000; 500,000; 600,000; 700,000; 800,000; or 1,000,000; preferably from 4,000 to 1,000,000 Daltons, more preferably from 10,000 to 1,000,000 Daltons, more preferably in the range of from 20,000 to 800,000 Daltons, more preferably in the range of from 50,000 to 700,000 Daltons, more preferably in the range of from 75,000 to 600,000 Daltons, more preferably in the range of from 100,000 to 500,000 Daltons, more preferably in the range of from 150,000 to 450,000 Daltons, and most preferably in the range of from 200,000 to 400,000 Daltons.
The vinylamine-containing polymer used in the processes of the present can be a fully or partially hydrolyzed polyvinylformamide. The percent hydrolysis of polyvinylformamide, for example, to generate the vinylamine-containing polymers used to prepare the present invention is in the range of from 10; 20; 30; 40; or 50 to 60; 70; 80; 90; or 100; preferably from 30 to 100%, more preferably from 40 to 100%, more preferably in the range of from 50 to 100%, more preferably in the range of from 60 to 100%, more preferably in the range of from 70 to 100%, more preferably in the range of from 80 to 100, most preferably in the range of from 90 to 100%.
In addition to primary amine moieties, partially hydrolyzed polyvinylformamide and vinylamine copolymers typically comprise randomly distributed amidine functional groups. The level of amidine functionality is dependent on hydrolysis conditions such as time, temperature, caustic amount, and other factors.
High Quality of DIN376 Metric Machine Taps-containing polymer, such as polyvinylamine, must first be adjusted to a stable pH below about 3.3. A pH below 3.0 is preferred, more preferably below 2.5 and a pH between 2.1 and 2.5 is most preferred. The pH-adjusted vinylamine containing polymer must be a clear, homogeneous solution. The pH adjustment can be made using mineral or organic acids. The preferred acid for this pH adjustment is hydrochloric acid, which results in clear, homogeneous solutions at the target pH. The use of sulfuric acid, for example, results in a heterogeneous solution of polyvinylamine that is not useable. Organic acids (e.g.,Hot Sales Wf-1325 3D Wood Carving Machine CNC Router) can also be used. Other commercially available acids include methylsulfonic acid, hydrobromic acid,20X2X20mm 20mm X 16mm X2mm PTFE (Teflon) Pall Ring in Good Quality.

In the following examples,Rubber Outsole Material Sport Style Light Safety Shoes, including stock preparation, refining and storage. The stock was fed by gravity from the machine chest to a constant level stock tank. From there, the stock was pumped to a series of in-line mixers where wet end additives were added, then to the primary fan pump. The stock was diluted with white water at the fan pump to about 0.2%W2 CO2 Laser Engraving Equipment for Wood/Plywood/Veneer/MDF/ Balsa. Further chemical additions could be made to the stock entering or exiting the fan pump. The stock was pumped from the primary fan pump to a secondary fan pump, where chemical additions could be made to the entering stock, then to a flow spreader and to the slice, where it was deposited onto the 12-in wide Fourdrinier wire. Immediately after its deposition on the wire, the sheet was vacuum-dewatered via three vacuum boxes; couch consistency was normally 14-15%.
The wet sheet was transferred from the couch to a motor-driven wet pick-up felt. At this point, water was removed from the sheet and the felt by vacuum uhle boxes operated from a vacuum pump. The sheet was further dewatered in a single-felted press and left the press section at 38-40%W2 CO2 Laser Engraving Equipment for Wood/Plywood/Veneer/MDF/ Balsa.

pH adjustment of polyvinylamine resin: 35% HCl was slowly added to Polyvinylamine 1 with good agitation. The pH was monitored as the HCl was added. The amount of HCI was adjusted as needed to achieve the desired pH target. The pH was rechecked after several hours to make sure the pH was stable. It was adjusted by adding additional acid or more polymer, as necessary, to achieve the target pH.
