The invention relates to a hydroxylated and/or carboxylated polyester resin, which comprises, in its structure, ester units formed from a polyol component a) comprising at least one polyol al) chosen from hydroxylated and/or epoxidized fatty acid triglycerides of general formula (I): R-CO2-(H)C-(CH2-CO2-R)2 (I) with R being the residue radical without a carboxyl group of a hydroxylated and/or epoxidized fatty acid RCO2H with R comprising from 13 to 21 carbon atoms and at least one hydroxyl and/or epoxy group. The invention also relates to a crosslinkable coating composition in an organic solvent medium comprising said resin, just like the coating which results from this use.

A polyester polyol is synthesized through an esterification reaction with a sebacic acid by-product fatty acid as a raw material; wherein the sebacic acid by-product fatty acid is refined from a by-product produced during preparing a sebacic acid from a castor oil; the sebacic acid by-product fatty acid includes, in weight percentage: a palmitic acid 15-25%, a stearic acid 10-16%, an oleic acid 45-57%, and a linoleic acid 12-28%. A method for preparing the polyester polyol is provided, as well as a polyurethane controlled-release fertilizer envelope and a polyurethane controlled-release fertilizer. The sebacic acid by-product fatty acid is used as a raw material to synthesize the polyester polyol because of a low price. The prepared fertilizer has excellent envelope and controlled-release performance, product structure performance is stable, cost performance is high, and degradation performance is sufficient after being applied to soil.

A thermoplastic polyester resin composition includes 0.05 to 10 parts by weight of an epoxy compound (B) and 0.001 to 1 part by weight of a hindered amine compound (C) with respect to 100 parts by weight of a thermoplastic polyester resin (A) having an amount of carboxyl groups of 50 eq/t or less. The thermoplastic polyester resin composition is capable of producing a molded article which is excellent in mechanical properties and heat resistance, as well as in long-term hydrolysis resistance, and has a small decrease in mechanical properties and hydrolysis resistance even when melt-processed at a high temperature of 270° C. or more.
