1. A copolymer comprising plural polyol monomeric units, said polyol monomeric units being acrylated and acylated or acetalized, wherein the acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, but less than the number of the hydroxyl groups of the polyol and have an average degree of acylation or acetalization which is 1 or more, but less than the number of the hydroxyl groups of the polyol, wherein the copolymer has a linear or branched-chain structure, and wherein the copolymer has a molecular weight (Mn) of at least 1 KDa.
