FIELD: polymer materials. ^ SUBSTANCE: invention, in particular, relates to curing polyester compositions. Polymer composition of invention includes, wt parts: binding agent (unsaturated polyester resin or acrulic oligomer, or mixture thereof) 100, abrasive filler 110-160, ground silica (Aerosil) 0.5-5.2, cumene hydroperoxide initiator 0.2-0.4, and accelerator 0.5-0.7, said accelerator being a complex compound obtained by interaction of vanadium pentoxide with orthophosphoric acid/water/butanol mixture in amount 0.03-0.6% on the weight of binder. ^ EFFECT: optimized composition including non-expensive and high-efficiency accelerator. ^ 5 ex |
