摘要： A composition comprises 100 parts by weight of a vinyl chloride type resin and 25 to 200 parts by weight of a plasticizer, the vinyl chloride type resin being composed of 1 to 90% by weight of tetrahydrofuran-insoluble gel fraction and the balance of tetrahydrofuran-soluble fraction. This composition gives a rubbery elastomer having an excellent heat deformation resistance and an excellent matt finish and a small compression permanent set. Though it is close to rubber in properties, the composition has a moldability and processability similar to those of conventional thermoplastic resins, and can be formed into a sheet for interior material of automobile, a packing, a tube, etc.

摘要翻译： 组合物包含100重量份的氯乙烯类树脂和25-200重量份的增塑剂，氯乙烯类树脂由1至90重量％的四氢呋喃不溶性凝胶分数组成，余量为四氢呋喃 - 可溶性级分。 该组合物得到具有优异的耐热变形性和优异的亚光光泽度和小压缩永久变形的橡胶状弹性体。 虽然其性能接近于橡胶，但组合物具有与常规热塑性树脂相似的成型性和加工性，并且可以形成为用于汽车，包装，管等的内部材料的片材。
