| titleOfInvention | Unsaturated polyester resin compositions |
| abstract | A polymerizable resin composition consists essentially of (a) a polyester comprising the reaction product of at least one alpha, beta-ethylenically unsaturated dicarboxylic acid or anhydride and at least one dihydric alcohol; (b) an olefinically unsaturated comonomer for the said polyester; and (c) a stabilizing amount of cupferron. Preferred polyesters are derived from maleic anhydride and propylene glycol or dipropylene glycol. Specified comonomers (b) are styrenes, methyl methacrylate, diallyl phthalate, triallyl cyanurate and indene. In Examples 1 to 4, a phthalic anhydride/maleic anhydride/propylene glycol polyester is dissolved in styrene and silica, polyethylene oxide, cupferron and methyl ethyl ketone peroxide are added to the solution, whereas in Examples 5 to 11 the said polyester-styrene solution is mixed with t-butyl hydroquinone, cupferron and a catalyst selected from t-butyl perbenzoate, benzoyl peroxide, hydroheptyl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, bis (1 - hydroxycyclohexyl) - peroxide and 2,5-dimethyl - hexane - 2,5 - diperbenzoate. The same polyesterstyrene solution is blended in Example 12 with cobalt octoate, diethylaniline, silica, polyethylene oxide, methyl ethyl ketone peroxide and cupferron and cured. In Example 13 the said solution is blended with hydroquinone, cupferron dissolved in betamethoxyethanol, t-butyl hydroquinone dissolved in methanol, silica and polyethylene oxide, the resulting mixture being homogenized by ultrasonic vibration prior to the addition of methyl ethyl ketone peroxide. |
