New cationic diagonally cross linked copolymer useful for improving physical characteristics of keratinic fibers (preferably human hair) and for styling and conditioning hairs

摘要

Cationic diagonally cross linked copolymer (I) (obtained by copolymerisation of (A) at least one monomer A, monomer B, at least doubly unsaturated monomer C, which is copolymerisable with monomers A and B, where in the copolymer, the quantity of B and C is 35-99 wt.% and 0.5-10 wt.%, respectively related to total weight amounts of A and B) is new. Cationic diagonally cross linked copolymer (I) (obtained by copolymerisation of (A) at least one monomer A of formula (H2C=C(R1)-C(=O)-X-R3), monomer B of formula (H2C=C(R1)-C(=O)-X-(CH2)n-N+(R4)(R6)-(R5) (Y-) and at least doubly unsaturated monomer C, which is copolymerisable with monomers A and B, where in the copolymer, the quantity of B and C is 35-99 wt.% and 0.5-10 wt.%, respectively related to total weight amounts of A and B) is new. R1H or CH3; X : O or NR2; R2H or 1-6C alkyl; and R31-12C alkyl; n : 1-8; R4-R61-8C alkyl, each carry one hydroxy- or amino group; and X : halo or mono alkyl sulfate. Independent claims are also included for: (1) the preparation of (I); (2) agent for the treatment of keratinic fibers comprising at least (I); and (3) a method for improving the physical characteristics of keratinic fibers, comprising applying a agent in an effective quantity on the fibers.
