    摘要: The present invention provides thermoplastic hydroxy-functional polyesters. The polyesters have at least 10 sequential units, wherein the sequential units consist of units selected from units represented by the following formula (1) and units represented by the following formula (2); Wherein each of R1 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; each of R2 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; each of R3 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; Each of R4 independently represents a substituted or unsubstituted homoalkyl or heteroalkyl group; and said moiety having no fewer than 1 unit represented by formula (1) and no fewer than 1 unit represented by formula (2). The present invention further provides processes for making hydroxyfunctional polyesters, such as polymerizing epoxidized fatty acids in the presence of an onium salt, and compositions and articles that include or are derived from the hydroxyfuntional polyesters

    摘要: A curable composition including (a) at least one cyclic diamine, (b) at least one non-heterocyclic amine that has a pKa value of approximately 9.5 to about 12 at 25° C. for the most basic amine group in the non-heterocyclic amine molecule, (c) at least one epoxy resin, and (d) at least one alkylated phenol; (i) wherein the equivalents of the amine hydrogens from the cyclic diamine compared to the total amine hydrogens from both the cyclic diamine and the non-heterocyclic amine in the composition are greater than about 5%; (ii) wherein the ratio of the equivalents of the total amine hydrogens in the composition to the equivalents of the total epoxies in the composition is greater than or equal to about 1; and (iii) wherein the alkylated phenol is in an amount greater than about 10 wt % of the curable composition.
