CATALYST COMPOSITION FOR POLYMERIZATION AND CURING

PURPOSE:To obtain the title composition of improved colorability without detriment to its low-temperature curability, by dissolving an organic acyl peroxide in a solvent mixture based on dioctyl phthalate. CONSTITUTION:3.5wt% or below organic acyl peroxide (e.g., benzoyl peroxide) is dissolved in di...

Zusammenfassung:	PURPOSE:To obtain the title composition of improved colorability without detriment to its low-temperature curability, by dissolving an organic acyl peroxide in a solvent mixture based on dioctyl phthalate. CONSTITUTION:3.5wt% or below organic acyl peroxide (e.g., benzoyl peroxide) is dissolved in dioctyl phthalate or a solvent mixture formed by dissolving at least 80% dioctyl phthalate in a solvent (e.g., benzene) to obtain a catalyst composition for polymerization and curing. Said catalyst composition in an amount to provide a catalyst amount of 0.01-5.0wt% is added to a polymerizable liquid product comprising methyl methacrylate, a monomer mixture based thereon or a prepolymer thereof, and the mixture is cured.
