Disclosed are compositions comprising polyester macromers containing in one or more chains the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes, and optionally one or more dihydrocarbyl dicarboxylates, and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols. The chains may contain the residue of the one or more diols and one or more diesters comprising one or more diesters 1,1-diester-1 alkenes and optionally one or more dihydrocarbyl dicarboxylates randomly disposed along the chains. Disclosed are methods of preparing the polyester macromers and incorporating them in a variety of polyester containing compositions such as coatings and films.
本发明涉及一种聚酯大分子组分,其中包括含有一种或多种二元醇和一种或多种二元酯的残基的聚酯大分子,其中一种或多种二元醇和一种或多种二元酯的残基沿着链交替出现,其中部分二元酯为1,1-二酯-1-烯烃,并且选配一种或多种二烷基二羧酸酯,至少一个端点包括1,1-二酯-1-烯烃中的一个残基,其中一个或多个端点可以包括一种或多种二元醇的残基。链可以包含沿着链随机分布的一种或多种二元醇和一种或多种二元酯的残基,其中包括一种或多种1,1-二酯-1-烯烃的二元酯和选配一种或多种二烷基二羧酸酯。本发明还涉及制备聚酯大分子的方法,并将其纳入各种聚酯含量组分中,例如涂料和薄膜。
