Embodiment Construction

[0084] Preparation of A / copolymer:

[0085] Preparation of polymer A1: polymer prepared according to the invention.

[0086]Load the following fractions into a reactor equipped with a mechanical stirring system, condenser, thermometer and nitrogen inlet:

[0087] -19.7g (27wt%) 64% dimethyl diallyl ammonium chloride solution

[0088] -62.7g (68wt%) 50% acrylamide solution

[0089] - 2.1 g (5 wt%) mPEG 2000MA (Visiomer mPEG 2005MA, Evonik). This is a methoxypolyethylene glycol methacrylate with a molecular weight of 2000 g / mol.

[0090] -365.5g water

[0091] The reaction medium is deoxygenated under nitrogen flow and heated to 75°C.

[0092] Separately, an initiator solution was prepared by introducing 0.45 g of 2,2' azobis(2-amidinopropane) dihydrochloride (V50, Wako) into 20 g of water.

[0093] When the temperature of the medium reached 75° C., the continuous feed of the initiator solution was started. The addition of this solution was continued for 120 minutes, ...

Abstract

A water-soluble copolymer comprising, by mass relative to the total mass of the copolymer: 1 to 40% of at least one cationic monomer; 59.99 to 98% of at least one nonionic monomer; 0.01 to 10% of at least one monomer of formula (I); in which: R1 is a hydrogen atom or a methyl radical; Z is a divalent group —C(═O)—O—, or —(═O)—NH—; n is an integer between 2 and 200; R2 is a hydrogen atom or a carbon-containing radical which is saturated or unsaturated, optionally aromatic, linear, branched or cyclic, comprising 1 to 30 carbon atoms, and from 0 to 4 heteroatoms chosen from the group comprising O, N and S; the copolymer having a cationic charge density between 0.05 and 3 meq / g.

Description

technical field [0001] The present invention relates to the technical field of polymers having a "comb" structure, and more particularly, to cationic polymers having a comb structure having hydrophilic side chains. These polymers with a comb structure have been found to be particularly suitable for use in the cosmetic and detergent fields. Background technique [0002] Comb-structured polymers have a comb-like structure. In other words, such polymers contain a main chain incorporating multiple side chains with different properties and variable lengths. For example, these side chains may have hydrophilic and / or hydrophobic properties. They consist of ethylene oxide units, propylene oxide units and alkyl-type units and their analogues, in the case of poly(ethylene oxide)-type side chains, which have a length of 2-500 units, preferably 5- 200 units of length. [0003] Comb-structure polymers known from the prior art include in particular polymers based on polyethylene glyco...
