Abstract
A resin composition is prepared by reacting components comprising dibasic acid, diamine, polyol and monoalcohol, wherein (a) at least 50 equivalent percent of the dibasic acid comprises polymerized fatty acid; (b) at least 50 equivalent percent of the diamine comprises ethylene diamine; (c) 10-60 equivalent percent of the total of the hydroxyl and amine equilvalents provided by diamine, polyol and monoalcohol are provided by monoalcohol; and (d) no more than 50 equivalent percent of the total of the hydroxyl and amine equivalents provided by diamine, polyol and monoalcohol are provided by polyol. This resin composition may be formulated into, for example, personal care products, fragrance releasing products and candles.
Claims31
A resin composition prepared by reacting components comprising dibasic acid, diamine, polyol and monoalcohol, wherein
- (a) at least 50 equivalent percent of the dibasic acid comprises polymerized fatty acid;
- (b) at least 50 equivalent percent of the diamine comprises ethylene diamine;
- (c) 10-60 equivalent percent of the total of the hydroxyl and amine equilvalents provided by diamine, polyol and monoalcohol are provided by monoalcohol;
- and
- (d) no more than 50 equivalent percent of the total of the hydroxyl and amine equivalents provided by diamine, polyol and monoalcohol are provided by polyol.
A resin composition prepared by reacting components consisting essentially of dibasic acid, diamine, polyol and mono-alcohol, wherein
- (a) at least 50 equivalent percent of the dibasic acid comprises polymerized fatty acid;
- (b) at least 50 equivalent percent of the diamine comprises ethylene diamine;
- (c) 10-60 equivalent percent of the total of the hydroxyl and amine equilvalents provided by diamine, polyol and monoalcohol are provided by monoalcohol;
- and
- (d) no more than 50 equivalent percent of the total of the hydroxyl and amine equivalents provided by diamine, polyol and monoalcohol are provided by polyol.
A method for preparing a resin composition comprising ester-terminated poly(ester-amide), the method comprising reacting w equivalents of hydroxyl from polyol or a reactive equivalent thereof, x equivalents of carboxylic acid from diacid or a reactive equivalent thereof, y equivalents of amine from diamine, and z equivalents of hydroxyl from monoalcohol or a reactive equivalent thereof under reactions conditions to provide a resin composition having an acid number of less than 20 and an amine number of less than 20, wherein at least about 50% of the carboxylic acid equivalents are from polymerized fatty acid, at least about 50% of the amine equivalents are from ethylene diamine, and mono-alcohol is substantially the only monofunctional reactant used to form the resin.
