ABSTRACT:
Disclosed is are high molecular weight copolyester compositions which possess high melt viscosity and melt strength which render them foamable with a wide range of foaming agents. The copolyesters consist essentially of (A) diacid residues comprising (i) from about 99.9 to about 95 mol % of residues of an aromatic dicarboxylic acid having 8 to 12 carbon atoms and (ii) from about 0.1 to about 5.0 mol % of residues of an aromatic dicarboxylic acid sulfonate monomer containing at least one divalent metal sulfonate group attached to an aromatic nucleus, and (B) diol residues comprising residues of at least one aliphatic or cycloaliphatic diol having 2 to 8 carbon atoms, the mol % being based on 100 mol % dicarboxylic acid residues and 100 mol % diol residues.
