摘要： The production of esters via the reaction of an epoxide with a carboxylic acid hasbeen shown to give improved activity when a strong base macroporous anion exchange resin having an acrylic backbone is used in place of a styrene-divinylbenzene based anion exchange resin having an equivalent exchange capacity. Excellent results are obtained when acrylic acid and propylene oxide are reacted together in the presence of strong base macroporous anion exchange resins which have an acrylic backbone.

摘要： Strong base anion exchange resins that contain quaternary ammonium groups derived from higher molecular weight amines, such as triethylamine or tripropylamine instead of trimethylamine, have a higher reactivity for catalyzing the reaction of an epoxide compound with an acid compound to form an ester.

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
