Abstract

Curable liq. epoxide gp.-contg. graft cpolymers are prepd. by reacting (a) 30-80 wt.% of a liq. epoxide cpd. with >1 epoxide gp./mol, a viscosity of 15-14000 cP at 25 degrees C and an epoxide eqiv. wt. of 120-450, dissolved in an inert solvent with a b. pt. of 60-150 degrees C, with (b) 70-20 wt.% of a mixt. consisting of (i) 2-10 wt.% 3-5c ethylenically unsatd. acids or anhydrides, (ii) 70-95 wt. % acrylic acid esters of 1-18C aliphatic monoalcohols and (iii) 3-25 wt.% (meth)acrylonitrile, where (i)+(ii)+(iii) = 100% and (a)+(b) = 100%. The reaction is carried out at 60-120 degrees C in the presence of a free radical catalyst until graft polymerisation is complete, after which the solvent is opt. removed under reduced press. at 130 degrees C. Prods. are stable for several months at 40 degrees C and are compatible with known epoxy resin hardeners. They cure at relatively low temps. to solvent- and weather resistant coatings. The resins are useful binders in solvent free coating formulations which cure without pollution of the atmos.
