| description | PURPOSE:To provide the titled compsn. having excellent moldability and impact resistance, consisting of a reaction product between an unsaturated polyester and an unsaturated glycidyl compd., an unsaturated monomer and an alkaline earth metal oxide or hydroxide. CONSTITUTION:An unsaturated polyester having an MW of 1,000-4,000 and an acid value of 15-50mgKOH/g, obtd. by reacting an alpha,beta-unsaturated dibasic acid (anhydride) [e.g., maleic acid (anhydride)] with a glycol (e.g., ethylene glycol) is reacted with an unsaturated glycidyl compd. (e.g., allyl glycidyl ether) in an amount satisfying the formula in the presence of a catalyst (e.g., LiCl) and an oxidative polymn. inhibitor (e.g., hydroquinone) at 50-180 deg. for 10min-2 hr to obtain a reaction product (A) having an acid value of 5-30mg KOH/g. 10-70wt% reinforcing fiber is impregnated with a resin compsn. obtd. by blending 100pts.wt. of the combined amount of 80-40wt% component A and 20-60wt% unsaturated monomer (B) (e.g., styrene) with 0.3-3pts.wt. alkaline earth metal oxide or hydroxide (C). |
