混杂组合物
摘要：
一种混杂组合物，其包括异氰酸酯、具有至少一个碳-碳双键和至少一个羟基的聚酯、存在量为5至30重量％的蓖麻油、催化剂和溶剂。可使用多种方法形成混杂组合物。该方法可包括将异氰酸酯和蓖麻油结合以形成第一加合物，将聚酯、溶剂和催化剂结合以形成第二加合物，并将第一加合物和第二加合物结合。或者，该方法可包括将蓖麻油、溶剂和聚酯结合以形成第三加合物，将第三加合物与异氰酸酯结合，并将催化剂与第三加合物和异氰酸酯结合。或者，该方法可包括将催化剂和异氰酸酯组分结合以形成第四加合物，并将第三和第四加合物结合。
摘要（英）：

A hybrid composition includes an isocyanate, a polyester having at least one carbon- carbon double bond and at least one hydroxyl group, castor oil present in an amount of from 5 to 30 weight percent, a catalyst, and a solvent. The hybrid composition can be formed using various methods. The method may include combining the isocyanate and the castor oil to form a first adduct, combining the polyester, the solvent, and the catalyst to form a second adduct, and combining the first adduct and the second adduct. The method may alternatively include combining the castor oil, the solvent, and the polyester to form a third adduct, combining the third adduct with the isocyanate, and combining the catalyst with the third adduct and the isocyanate. The method may alternatively include combining the catalyst and the isocyanate component to form a fourth adduct, and combining the third and fourth adducts.
