摘要： The invention provides polymers comprising repeating units derived from (a) from 16% by weight to about 35% by weight of said polymer of at least one N-vinyl lactam monomer; (b) at least one monomer selected from the group consisting of functionalized and unfunctionalized C1-C6 alkyl (meth)acrylates, C1-C6 alkyl (meth)acrylamides and combinations thereof; and (c) at least one monomer selected from the group consisting of functionalized and unfunctionalized C8-C30 branched alkyl (meth)acrylates, C8-C30 branched alkyl (meth)acrylamides, and combinations thereof; wherein the polymer has a glass transition temperature of greater than about 45° C. The invention further provides various compositions, such as, personal care, sun care, coatings, and pharmaceutical compositions comprising the polymers described herein. The invention furthermore provides water-resistant sun care compositions comprising the polymers described herein. Subscripts x, y and z are described herein. (Formula (I))
