    Abstract: The invention relates to a method for producing copolymers by radical polymerisation of a) 5 to 95 wt. % of a monomer of formula (I), b) 95 to 5 wt. % of a monomer of formula (II), wherein R and R represent H, C1-C3-alkyl, R = H, C1 6-alkyl and n = 1 to 3 respectively and c) 0 to 40 wt. % of another fully or partially water-soluble monomer. The inventive method is characterised in that the polymerisation is carried out in an aqueous medium.

    Inventor： NEUBECKER KARIN ,  BLANKENBURG RAINER

    IPC: C08F2/06 ,  C08F4/34 ,  C08F26/06

    Abstract: The invention provides a process for preparing polymers of N-vinylcaprolactam by polymerizing A) 40 - 100 % by weight of N-vinylcaprolactam and B) 0 - 60 % by weight of a further monoethylenically unsaturated monomer which is copolymerizable with N-vinylcaprolactam and also polymers prepared by this process.
