ABSTRACT:
A process for producing acrylic polymers which have high thermal stability, are free of defects and have a low level of unreacted monomer. The process includes the polymerization at a high production rate of a methyl methacrylate syrup in the presence of a mixture of two peroxide initiators. The first initiator has a 5-minute half-life at temperatures between about 75.degree. C. to 100.degree. C. and emits a maximum of 1 mole of carbon dioxide per 2 moles of free radicals. The second initiator has a one minute half-life at temperatures of between about 105.degree. C. to about 125.degree. C. and emits a maximum of 1 mole of carbon dioxide per 1 mole of free radicals.
