| titleOfInvention | Foamable copolyesters containing divalent metal sulfonate groups |
| abstract | Disclosed 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 99.9 to 95 mol % of residues of an aromatic dicarboxylic acid having 8 to 12 carbon atoms and (ii) from 0.1 to 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. Particularly preferred is a polyethylene terephthalate modified with 5-sulfoisophthalic acid magnesium salt units. |
