    • A lactone chain-extended polyester polyol of the present invention comprises the reaction product of a lactone and a previously chain-extended phenolic-based hydroxyl compound. The previously chain-extended phenolic-based hydroxyl compound may comprise the reaction product of (i) a lactone or an alkoxylating agent selected from the group consisting of alkylene oxides and alkylene carbonates, and (ii) a phenolic aralkylation polymer comprising the reaction product of a phenolic monomer having at least two free reactive positions; a styrene derivative; and a coupling agent. The previously chain-extended phenolic-based hydroxyl compound also may be chain-extended by reacting with a lactam to produce a lactam chain-extended polyester polyamide. The polyols and polyamides of the present invention provide unique combinations of hard and soft functionalities, which translates into materials exhibiting a unique combination of toughness and hardness. These materials are especially suitable for use in high solids coatings and in the development of resins which can be readily processed into thermoset resins. The materials also may function as compatibilizers for thermoplastics.
    • 本发明的内酯链延长聚酯多元醇包括内酯与先前扩链的酚基羟基化合物的反应产物。 先前扩链的酚基羟基化合物可以包含(i)内酯或选自环氧烷烃和碳酸亚烷基酯的烷氧基化剂的反应产物,和(ii)包含以下的反应产物的酚芳烷基化聚合物: 具有至少两个自由反应位置的酚单体; 苯乙烯衍生物; 和偶联剂。 先前的链延长的酚基羟基化合物也可以通过与内酰胺反应来产生内酰胺链延长的聚酯聚酰胺来延伸。 本发明的多元醇和聚酰胺提供硬和软功能的独特组合,其转化为显示韧性和硬度的独特组合的材料。 这些材料特别适用于高固含量涂料和开发可以容易地加工成热固性树脂的树脂。 这些材料也可用作热塑性塑料的增容剂。
