    摘要: Modified unsaturated linear polymers have at least a first residue, a second residue and an acid residue. The first, second and acid residues correspond to a first, second and acid monomers used to prepare the polymers. The first monomer may be a diacid, anhydride, diacid ester or mixture thereof. The second monomer may be a diol or glycol. The acid monomer may be an aromatic dicarboxylic acid, different than the first monomer. The first residue is present in a concentration not less than about 7.5 mole % and the acid residue is present in a concentration ranging between 2.5 mole % and 12.5 mole %, based on the total mole monomer ratio of the polymer. The polymers have a glass transition temperature ranging from about 54.degree. C. to about 64.degree. C.
