    • The present invention is generally directed to a process for producing lactide-based polymers and the polymers produced by this process. The polymers of the present invention are terpolymers formed by the copolymerization of a lactide monomer, a linking monomer and an epoxy-terminated monomer. In one embodiment of the invention, the polymers may be formed from fluorine-containing monomers or aromatic ring-containing monomers. The disclosed materials may display improved hydrolytic and thermal characteristics as compared to previously known lactide-based materials. For example, the lactide based terpolymers may have a glass transition temperature over 60° C. For instance, lactide-based thermoplastic terpolymers of the present invention can have a glass transition temperatures of about 80° C. or higher. Lactide-based thermoset networks of the invention can have glass transition temperatures of up to about 200° C.
    • 本发明一般涉及一种生产基于丙交酯的聚合物的方法和通过该方法生产的聚合物。 本发明的聚合物是通过共聚丙交酯单体,连接单体和环氧基封端的单体形成的三元共聚物。 在本发明的一个实施方案中,聚合物可以由含氟单体或含芳环的单体形成。 与先前已知的基于丙交酯的材料相比,所公开的材料可以显示出改善的水解和热特性。 例如,基于丙交酯的三元共聚物可以具有超过60℃的玻璃化转变温度。例如,本发明的基于丙交酯的热塑性三元共聚物可具有约80℃或更高的玻璃化转变温度。 本发明的基于丙交酯的热固性网络可以具有高达约200℃的玻璃化转变温度
