Abstract: Isocyanate-modified polyester-epoxide polymer (i-PEEP) compositions are disclosed. The i-PEEP compositions comprise a reaction product of a polyepoxide compound, a polyisocyanate, and a polyester polyol composition. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.2 to 2. The i-PEEP index as defined herein is within the range of 100 to 200. The i-PEEP composition has a T g within the range of -30°C to 35°C. Low- and elevated-temperature processes catalyzed by bases or Lewis acids for making the i-PEEP compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for coatings, elastomers, adhesives, sealants, and other valuable products is assembled from readily available starting materials without reliance on the polyamines typically used to cure epoxy systems.

Abstract: Polyether-epoxide polymer compositions are disclosed. The compositions comprise a reaction product of a polyepoxide compound and a polyol composition comprising a polyether polyol. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.5:1 to 3:1. The polyether-epoxide composition has a Tg within the range of -40°C to 60°C. The polyether polyol has a hydroxyl value within the range of 150 to 800 mg KOH/g and an average hydroxyl functionality within the range of 3.5 to 8.0. In some aspects, the polyol composition further comprises a polyester polyol. Low- and elevated-temperature processes catalyzed by bases or Lewis acids for making the polyether-epoxide compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for coatings, elastomers, adhesives, sealants, and other valuable products is assembled from readily available starting materials without reliance on polyamines or polyisocyanates.

Abstract: Polyester-epoxide polymer (PEEP) compositions are disclosed. The PEEP compositions comprise a reaction product of a polyepoxide compound (eq. wt. 125 to 250 g/eq.) and a polyester polyol composition. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.8 to 3.5. The PEEP composition has a T g within the range of -40°C to 60°C. Elevated temperature-cure and low temperature-cure processes for making the PEEP compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for adhesives, coatings, elastomers, and other valuable products is assembled from readily available starting materials without reliance on polyisocyanates or polyamines. The PEEP compositions have increased elongation and lower T g when compared with traditional epoxy products.

Abstract translation: 公开了聚酯 - 环氧化物聚合物（PEEP）组合物。 PEEP组合物包含聚环氧化合物（当量125-250g / eq。）和聚酯多元醇组合物的反应产物。 环氧当量与羟基当量的比例在0.8至3.5的范围内。 PEEP组合物具有在-40℃至60℃范围内的T g。 也公开了用于制造PEEP组合物的升高的温度固化和低温固化方法。 在一种简单而又创新的方法中，可用于粘合剂，涂料，弹性体和其他有价值产品的新一类聚合物由易得的起始材料组装而不依赖于多异氰酸酯或多胺。 与传统环氧产品相比，PEEP组合物具有增加的伸长率和更低的Tg。
