An unsaturated polyester (i) having a weight-average molecular weight (Mw) of 1,000-100,000 and at least two carbon-carbon unsaturated bonds in the molecule thereof obtained by esterifying an unsaturated carboxylic acid (b) with a polyester-polyol (a) obtained by subjecting a polybasic carboxylic acid containing polymerized fatty acid and/or polymerize fatty acid ester to polycondensation with a polyhydric alcohol; and an unsaturated (poly)urethane having Mw of 1,000-100,000 and at least two carbon-carbon unsaturated bonds in molecule obtained by reacting said polyester-polyol (a), polyisocyanate (d) and compound (e) having active hydrogen and polymerizable carbon-carbon unsaturated bond. Said unsaturated polyester and unsaturated (poly)urethane exhibit excellent adhesive property, heat resistance, water resistance and flexibility after being cured.
一种不饱和聚酯(i),其重量平均分子量(Mw)为1,000-100,000,其分子中至少有两个碳碳不饱和键,该不饱和聚酯是通过将不饱和羧酸(b)与聚酯多元醇(a)酯化而得到的,聚酯多元醇(a)是通过将含有聚合脂肪酸和/或聚合脂肪酸酯的聚合基羧酸与多元醇缩聚而得到的;和一种不饱和(聚)氨基甲酸酯,其 Mw 为 1,000-100,000,分子中至少有两个碳碳不饱和键,由所述聚酯多元醇 (a)、多异氰酸酯 (d) 和具有活泼氢和可聚合碳碳不饱和键的化合物 (e) 反应而得。所述不饱和聚酯和不饱和(聚)氨基甲酸乙酯固化后具有优异的粘合性、耐热性、耐水性和柔韧性。
