  • RIGID-MATRIX COMPOSITION-GRADIENT COPOLYMERS WHICH ARE SOLUBLE AND/OR DISPERSIBLE IN WATER AND IN ORGANIC SOLVENTS
    Publication number: 20110172352
    Abstract: The invention relates to composition-gradient copolymers, comprising: repeat units resulting from the polymerization of at least one first monomer M1, the corresponding homopolymer of which exhibits a glass transition temperature Tg1 of less than 20° C., said repeat units representing from 15 to 40% by weight, with respect to the total weight of the copolymer; repeat units resulting from the polymerization of at least one second monomer M2, the corresponding homopolymer of which exhibits a glass transition temperature Tg2 of greater than 20° C., said repeat units representing from 45% to 65% by weight, with respect to the total weight of the copolymer; hydrophilic repeat units resulting from the polymerization of a least one third monomer M3, said repeat units representing from 10 to 25% by weight, with respect to the total weight of the copolymer.
