Cationic starch graft copolymers and novel process for the preparation of cationic starch graft copolymers |
| abstract |
A cationic starch graft copolymer is prepared by polymerization of monomers a) to d)n a) 20-80% by weight of acrylamide, methacrylamide or mixtures thereof, b) 3-20% by weight of at least one basic or cationic vinyl monomer; c) 0.005-1.5% by weight of at least one bifunctional or higher-functional crosslinking agent, d) 0-10% by weight of at least one nonionic or anionic vinyl monomer which differs from the monomers mentioned under a) to c)n nin the presence of a grafting base e)n e) 15˜70% by weight of at least one starch or one starch derivative,n nthe sum of a) to e) being 100% by weight. |
