The invention relates to a linear or branched polymer containing ester groups and at least one amidegroup in the backbone, having hydroxyalkylamide end groups and having a weight average molecular mass of &gE;800 g/mol. The invention also relates to an entirely or partly modified polymer. The polymer according to the invention can for example be obtained by reaction of a cyclic anhydride and an alkanolamine to form a &bgr;-hydroxyalkylamide, after which a polyesteramide is obtained through polycondensation. The polymers according to the invention can, for example, be used in thermosetting powder-paint compositions.

Condensation polymer containing hydroxyalkylamide groups

The invention relates to a linear or branched polymer containing ester groups and at least one amide group in the backbone, having hydroxyalkylamide end groups and having a weight average molecular mass of &gE;800 g/mol. The invention also relates to an entirely or partly modified polymer. The polymer according to the invention can for example be obtained by reaction of a cyclic anhydride and an alkanolamine to form a &bgr;-hydroxyalkylamide, after which a polyesteramide is obtained through polycondensation. The polymers according to the invention can, for example, be used in thermosetting powder-paint compositions.

The invention relates to the application of a resin composition containing

Coating materials curing at room temperature

Resin compositions comprising two resins A and B, wherein resin A consists of the reaction product of an epoxidized fatty acid ester of a polyvalent alcohol and a monovalent carboxylic acid and resin B consists of a carboxylic acid modified fatty acid ester of a polyvalent alcohol. These resins compositions are suitable for linoleum manufacture.

Process for preparing and processing a resin composition

The invention provides novel polyesters based on 100- 75 equivalent percent of a phthalic acid, 0- 25 equivalent percent of an aliphatic dicarboxylic acid and 150- 225 equivalent percent of a C.sub.5 - C.sub.12 diol. The polyesters can be admixed with amino resins and an acid catalyst to form a coating composition which can be stoved into a hard tough coating.
