Abstract
The present invention relates to a water-soluble polymer obtained by polymerization of at least a 2-dimethylaminoethyl acrylate monomer and/or its salts, in presence of at least a tocopherol and/or its derivatives, or a tocotrienol and/or its derivatives, and its uses.
Claims20
A water-soluble polymer obtained by polymerization of at least a 2-dimethylaminoethyl acrylate monomer and/or its salts, in presence of at least a tocopherol and/or its derivatives, or a tocotrienol and/or its derivatives.
A composition comprising:
- from 1 to 99,9999 w % of at least one 2-dimethylaminoethyl acrylate monomer and/or its salts;
- from 1 to 10 000 ppm of at least a tocopherol and/or its derivatives, or a tocotrienol and/or its derivatives, based on the amount of 2-dimethylaminoethyl acrylate monomer and/or its salts,
- Optionally at least an additive chosen from biocides, polymerization inhibitors, humidity absorbers, colour stabilisers.
Process for inhibiting the formation of vinyl acrylate resulting from a reaction between at least a 2-dimethylaminoethyl acrylate monomer and/or its salts and oxygen, comprising mixing said 2-dimethylaminoethyl acrylate monomer and/or its salts with a tocopherol and/or its derivatives, or a tocotrienol and/or its derivatives.
