阅读说明：本技术 由聚酯制成的预成型件 (Preform made of polyester ) 是由 D·戈登斯坦 于 2019-07-29 设计创作，主要内容包括：本发明涉及用于以吹塑方法制造塑料容器的由聚酯制成的预成型件,其具有管状预成型件主体,所述管状预成型件主体在其一个纵向端部处被设计为封闭的,并且在其另一个纵向端部处具有设有浇铸开口的颈部部分。所述聚酯基本上基于呋喃二羧酸和二醇,其中所述二醇的第一部分源自于螺环化合物的组且第二部分源自于常规二醇的组。(The invention relates to a preform made of polyester for producing a plastic container in a blow-molding method, having a tubular preform body which is designed to be closed at one longitudinal end thereof and has a neck portion provided with a casting opening at the other longitudinal end thereof. The polyesters are essentially based on furan dicarboxylic acids and diols, wherein the first part of the diols is derived from the group of spiro compounds and the second part is derived from the group of conventional diols.)
