Polyestercarbonate containing divalent residue of polymerized alkadiene monomer

摘要

An aromatic ester carbonate resin comprised of: (i) at least one recurring structural unit represented by the formula <IMAGE> (ii) at least one recurring structural unit selected from structural units represented by the formulae <IMAGE> <IMAGE> or mixtures thereof; and (iii) at least one recurring structural unit represented by the formula <IMAGE> (iv) at least one recurring structural unit selected from structural units represented by the formulae <IMAGE> <IMAGE> or mixtures thereof; wherein R is independently selected from halogen, monovalent hydrocarbon radicals, or monovalent hydrocarbonoxy radicals, W is selected from divalent hydrocarbon radicals, <IMAGE> A is the divalent residue of at least one polymerized conjugated alkadiene and has a weight average molecular weight of at least about 600, m is independently selected from integers having a value of from 0 to 4, and b is either zero or one, and wherein B is the divalent residue of an ester precursor.
