Process for making polyester/polyester elastomer compositions |
| abstract |
Processes to produce a polyester composition are provided comprising a) polymerizing at least one dicarboxylic acid and at least one diol to produce a rigid polyester having a Tg greater than 60°C; b) polymerizing at least one dicarboxylic acid, at least one diol, and at least one polyol to produce a polyester elastomer having a Tg less than 50°C; and c) contacting the rigid polyester with the polyester elastomer and at least one chain extending additive to produce the polyester composition; wherein the polyester composition has an enthalpy of melting of 3 cal/gm or less; wherein the polymerizing in steps a) and/or b) is conducted in the presence of at least one primary antioxidant; and wherein the polymerizing in steps a) and/or b) is conducted in the presence of at least one secondary antioxidant. |
