Polymers comprised of fully and partially hydrolyzed poly (vinyl acetate) and ketene dimer units and aqueous solutions containing such polymers.

摘要

Polymers having the general idealized structure: wherein a, b and c represent the number of monomer units of each respective monomer, the sum of a and b is 200 to 5000, b is the product of a multiplied by 0 through 0.25, c/(a + b) = 0.0001 to 0.006, m is 5 to 21, and the sum of m and n is 10 to 42, and their use to increase the viscosity of aqueous solutions, are disclosed.
