ABSTRACT:
Disclosed is a solid thermoplastic acrylic copolymer having a weight average molecular weight of 4,000 to 30,000 for the use as a material for powder paint capable of forming a smooth surface which is produced by copolymerizing, preferably in a suspension copolymerization method, comprising
(1) 3 to 30% by weight of at least one comonomer of the formula (I'): ##STR1## (2) 1 to 50% by weight of at least one comonomer selected from the compounds of the formulae (II') and (III'): ##STR2## and (3) 20 to 96% by weight of at least one comonomer of the formula (IV'): ##STR3## wherein R.sub.1, R.sub.1a and R.sub.1b are respectively a hydrogen atom or methyl group, R.sub.2 is an alkyl group of C.sub.1-8 or a cycloalkyl group of C.sub.6-8, R.sub.3 is an alkylene group of C.sub.2-6, R.sub.4 is an aliphatic group of C.sub.2-12 optionally containing a carboxyl group or an aromatic group of C.sub.6-12 optionally containing a carboxyl group, R.sub.5 is an aliphatic group of C.sub.1-18 optionally containing a hydroxyl group or an aromatic group of C.sub.6-18 optionally containing a hydroxyl group, n is 1 or 2 and X is an ester, nitrile, amide, R.sub.6 COO-- wherein R.sub.6 is an alkyl of C.sub.1-18, glycidylester, glycidylether, or an aromatic group of C.sub.6-18 or a halogen atom, at a pH of 7 or less in the presence of a catalyst.
