Abstract

本发明提供了可以膨胀成具有结点和原纤维结构的微孔制品的PLA聚合物。原纤维包含PLA聚合物链，所述聚合物链沿着原纤维轴取向。另外，PLA聚合物具有大于约3.8 dL/g的特性粘度和大于约150,000g/mol的计算的分子量。 PLA聚合物制品可通过本体聚合形成，其中PLA本体聚合物被制成预制件，所述预制件随后在高于PLA聚合物的玻璃化转变温度且低于PLA聚合物的熔点的温度下膨胀。在替代性实施方案中，将PLA聚合物粉末润滑，润滑的聚合物经受压力和压缩以形成预制件，并且使预制件膨胀以形成微孔制品。预制件和微孔制品均在高于PLA聚合物的玻璃化转变温度且低于PLA聚合物的熔点的温度下形成。
