Abstract
An advanced addition product containing hydroxyl groups is prepared from the reaction of specific mononuclear hydantoin glycidyl compounds with non-aromatic dicarboxylic acids of 9 to 44 carbon atoms and, optionally mono-carboxylic acids of 6 to 18 carbon atoms. The above advanced addition products are heat curable with suitable curing agents for hydroxyl containing materials to afford cured compositions exhibiting excellent weathering, color stability and chalking resistance.
Claims14
An advanced addition product containing hydroxyl groups, which is obtained by heating a mixture comprising:
- (a) one equivalent of a mononuclear hydantoin glycidyl compound selected from the group consisting of
- (1) a compound of the formula I ##STR8## (2) a compound of the formula II ##STR9## (3) a compound of the formula III ##STR10## (4) any combination of compounds of the formulae I, II, or III, wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6 and R.sub.7 are independently alkyl of 1 to 8 carbon atoms or cycloalkyl of 5 to 6 carbon atoms or R.sub.1 and R.sub.2 together, R.sub.3 and R.sub.4 together and R.sub.6 and R.sub.7 together are tetramethylene or pentamethylene, and R.sub.5 and R.sub.8 independently are hydrogen or methyl;
- (b) 0.7 to 2.0 equivalents of a non-aromatic dicarboxylic acid of 9 to 44 carbon atoms;
- and
- (c) 0.0 to 0.5 equivalents of a monocarboxylic acid of 6 to 18 carbon atoms.
