摘要 |
An elastomeric copolyester resin having high melt strength and capable of being blow-molded. The copolyester resin is made by adding to the polymerizing or initial mixture small amounts of a heat stable chain branching agent having three or more carboxyl groups, hydroxyl groups, or combinations thereof.
