摘要： The invention is directed to a process for the production of polyurethanes suitable for thermoplastic processing comprising mixingI. at least 75% by weight of preformed thermoplastic polyurethane elastomers, or of a blend of(A) substantially bifunctional, compounds(B) substantially bifunctional chain-extending agents(C) organic diisocyanates and optionally(D) lubricants or other known additivessaid blend characterized in that it contains no peroxides and polymerization initiators which decompose into radicals under the effect of actinic light and further in that the molar ratio of the sum of said (A) and said (B) to said (C) is between 0.9 to 1.1, withII. (E) from 4 to 24% by weight of a crosslinking agent andIII. (F) from 0.01 to 3% by weight of a polymerization inhibitor and/or an antioxidant,by adding said II and said III to said I at a temperature below 230.degree. C., and the cooling the mixture to below 130.degree. C. in less than 5 minutes in a continuous extruder and optionally granulating the resulting polyurethane.
摘要翻译：本发明涉及一种用于生产适用于热塑性加工的聚氨酯的方法，其包括将I.至少75重量％的预成型热塑性聚氨酯弹性体或（A）基本上双官能的化合物（B）的混合物（B）基本上是双功能链 - 扩展剂（C）有机二异氰酸酯和任选的（D）润滑剂或其它已知的添加剂，所述共混物的特征在于其不含过氧化物和聚合引发剂，其在光化光的作用下分解成自由基，并且进一步地，总和的摩尔比（A）和所述（B）至（C）之间的比例在0.9至1.1之间。（E）4至24重量％的交联剂和III。（F）0.01〜3重量％的阻聚剂和/或抗氧化剂，通过在低于230℃的温度下将所述II和所述III加入到所述I中，并将混合物冷却至130℃以下。在连续挤出机中在不到5分钟的时间内，并任选地造粒得到的聚氨酯。
