  Among other things, the present disclosure provides compositions and methods for an elastomeric cross-linked polyester material. Such an elastomeric cross-linked polyester material, in some embodiments, comprises a plurality of polymeric units of the general formula (-A-B—)p, wherein p is an integer greater than 1; and a plurality of urethane cross-links each of which covalently links two polymeric units to one another, which two linked polymeric unit each had at least one free hydroxyl or amino group prior to formation of the crosslink.

  除其他外，本公开提供了一种弹性交联聚酯材料的组合物和方法。在某些实施例中，这种弹性交联聚酯材料包括通式（-A-B-）p 的多个聚合物单元，其中 p 是大于 1 的整数；以及多个聚氨酯交联剂，其中每个交联剂将两个聚合物单元彼此共价连接，这两个连接的聚合物单元在形成交联剂之前各自至少有一个游离羟基或氨基。

  A polyester resin composition for profile extrusion molding comprising an amorphous polyester, at least one component selected from the group consisting of a crystalline polyester and a nucleating agent, and optionally a reactive compound; a polyester resin composition for profile extrusion molding comprising a polyester resin, and a reactive compound having a weight average molecular weight of 200 to 500,000; and a profile shape comprising a resin having a reduced viscosity ratio of 1.01 to 3.00, a reduced viscosity ratio being a ratio of a reduced viscosity of a resin after molding to that of a resin before molding. They do not suffer from sagging in the molding process, they improve the shape accuracy at corners and edges of profile shapes from a die to a sizing step and also resistance to whitening on bending in transparent products, and can provide profile shapes having good solvent resistance and detergent resistance.

  一种用于型材挤压成型的聚酯树脂组合物，包括无定形聚酯、至少一种选自由结晶聚酯和成核剂组成的组的组分，以及可选的反应性化合物；一种用于型材挤压成型的聚酯树脂组合物，包括聚酯树脂和重量平均分子量为 200 至 500,000 的反应性化合物；以及一种型材形状，包括粘度降低率为 1.降低粘度比是指成型后树脂的降低粘度与成型前树脂的降低粘度之比。它们在成型过程中不会出现下垂现象，可提高异型材从模具到定型步骤的角和边缘的形状精度，还可防止透明产品在弯曲时发白，并可提供具有良好耐溶剂性和耐洗涤剂性的异型材。
