    • The present disclosure is concerned with a novel transparent polyurethane polyurea which is particularly suitable for lamination to glass and glasslike transparent plastics. The polymer is the reaction product of high molecular weight diols, optionally low molecular weight diols, dihydroxy carboxylic acids, diisocyanates with only aliphatically and cycloaliphatically bound isocyanates and organic diamines having aliphatically and cycloaliphatically bound primary amino groups. It has specified contents of carboxyl groups and urea groups, and it has a minimum shear modulus at both 20.degree. and 60.degree. C.The present disclosure is also concerned with a process for synthesizing such polymers. A preferred method is to react the diisocyanate and hydroxyl bearing compounds to prepare an isocyanate terminated prepolymer and chain extend with the diamine.Also discussed are the production of film from these polymers by extrusion and solution casting, the production of laminates with glass and glasslike plastics and the laminates so produced. The solution cast or extruded films can be laminated to these substrates by the application of heat and pressure.
    • 本公开涉及一种新型的透明聚氨酯聚脲,其特别适用于层压至玻璃和玻璃状透明塑料。 聚合物是高分子量二醇,任选的低分子量二醇,二羟基羧酸,仅具有脂肪和环状结合的异氰酸酯的二异氰酸酯和具有脂族和环烯键合的伯氨基的有机二胺的反应产物。 具体规定了羧基和脲基的含量,在20℃〜60℃都具有最小的剪切弹性模量。本发明还涉及合成这些聚合物的方法。 优选的方法是使二异氰酸酯和含羟基的化合物反应以制备异氰酸酯封端的预聚物,并且链与二胺延伸。 还讨论了通过挤出和溶液流延从这些聚合物生产膜,生产具有玻璃和玻璃状塑料的层压材料以及如此生产的层压材料。 可以通过施加热和压力将溶液流延或挤出的膜层压到这些基底上。
