Abstract: Low-mol. wt. copolymers (I) with a wt.-average mol. wt. (Mw) of less than 3500 contain at least 20 wt.% of components with branched side chains, obtd. by the reaction of (aa) glycidyl ester(s) of satd. aliphatic monocarboxylic acids with a tert. or quat. alpha -C atom; and (ab) at least two unsatd. comonomers, at least one of which contains at least one COOH gp., under radical copolymerisation conditions. Also claimed are (i) prepn. of (I) by heating component (aa) to 210-260 degrees C and reacting with component (ab) (which contains at least 2.0 wt.% of a COOH gp.-contg. monomer) in the presence of radical initiator(s), to a degree of conversion of at least 95 (pref. at least 97.5) %; (ii) polymer mixts. contg. (I), obtd. by reaction of (aa) and (ab) as above in at least two time intervals with a constant temp. in each interval, using at least two different reaction temps., at least one of which is in the range 210-260 degrees C; (iii) polymer mixts. contg. (I) and other polymers etc.; (iv) binders for coating materials contg. (I) or the above polymer mixts.; (v) coating materials contg. binders as above and hardeners such as amino resins, capped or uncapped polyisocyanates or organic cpds. with acid and/or anhydride gps.

(I) are obtd.: (A) by reacting (a) 7-33C (cyclo)aliphatic mono-epoxides (a1), at least 20 wt% of which comprises monoepoxides with a tert. or quat. C atom with (b) 2-30C amines with at least 2 prim. or sec. amino gps. not attached directly to an aromatic ring; or (B) by reacting (a) 8-50C (cyclo)aliphatic diepoxides (a2) with (b) 4-30C prim. or sec. mono-amines with amino gps. not directly attached to aromatic rings, of which at least 20 wt% comprises mono-amines with at least one tert. or quat. C atom; or (C) by reacting (a1) with (b), the corresp. proportions of mono-amine and mono-epoxide with tert. or quat. C atoms being a% and b% respectively, where a + b = 20 and both a and b are greater than zero.
