摘要：
A linear, block copolymer, which is useful in cosmetics and improves the styling power and hold of hair laquer, adhesion of nail varnish and hold/adhesion of makeup, includes at least two blocks having different glass transition temperatures, Tg; where at least one of said blocks has a glass transition temperature of 20° C. to −100° C., and wherein the at least one block having a Tg of 20° C. to −100° C. is a copolymer B having a first monomer wherein the Tg of the corresponding homopolymer is in the range from more than 20° C. to 200° C., and a second monomer wherein the Tg of the corresponding homopolymer is in the range from 20° C. to −100° C.
