Abstract:
A thermoplastic polyester resin represented by general formula (1) or (2) which comprises monomer units derived from an acid ingredient (A) comprising (A1) an aromatic dicarboxylic acid and/or an aliphatic dicarboxylic acid, (A2) an aliphatic hydroxycarboxylic acid, and (A3) an aliphatic dicarboxylic acid having a carbon-carbon unsaturated bond in the molecule and monomer units derived from a glycol ingredient (B) comprising an aliphatic diol,said thermoplastic polyester resin having a melt index MI (measured at 230.degree. C. under a load of 2.16 kg) of from 1 to 50: ##STR7## wherein Ra1 is an aromatic and/or aliphatic hydrocarbon group (derived from monomer (A1));Ra2 is a hydrocarbon group (derived from monomer (A2));Ra3 is an aliphatic hydrocarbon group having a C.dbd.C bond (derived from monomer (A3));Rb is a hydrocarbon group (derived from monomer (B)); andl, m, n, p and q each is a positive integer; ##STR8## wherein Ra1 is an aromatic and/or aliphatic hydrocarbon group (derived from monomer (A1));Ra2 is a hydrocarbon group (derived from monomer (A2));Ra3 is an aliphatic hydrocarbon group having a C.dbd.C bond (derived from monomer (A3);Rb is a hydrocarbon group (derived from monomer (B)); andl, m, and n each is a positive integer.
