Paper Glyoxalated poly

To enhance the shelf life of finished paper product, the step 1 product was applied below its critical micelle concentration (CMC). Materials additized above the CMC formed insoluble gels when aged for 8 days at 73°C. The CMC ranges was determined using glyoxalated poly(vinylamide-co-diallyldimethyl-ammonium chloride) containing 90 wt% vinylamide and are provided in Table 1. [Pg.50]

Some commercial low molecular weight polyacrylamides (LMPAM) are manufactured in solution and sold at 10-50% solids. For example, LMPAM containing DADMAC comonomer is made at 40% solids and can be reacted with glyoxal to produce a strengthening resin for paper. Furthermore, LMPAM hydrolyzed with sodium hydroxide to polyacrylate is manufactured at 30% solids and is used as an antisealant. High molecular weight poly(acrylamide) is also prepared in solution at 2-6 wt% solids and is often further modified using, for example, the Mannich reaction. [Pg.107]
