Abstract
An acrylic-based particulate filled polymeric composition is provided which is curable at atmospheric pressure and ambient temperature and has a pour to pull time of less than about 4 hours. The acrylic-based particulate filled polymeric composition comprises an intimate blend of a polymerization syrup, a filler, and minor effective amount of crosslinking agent, a polymerization catalyst, a quaternary compound and a polymerization initiator. To enhance and reduce the pour to pull time of articles molded or cast from the acrylic-based particular filled polymeric composition, an effective miner amount of a reaction modifier, such as trimethylpropane triacrylate, can be incorporated into the polymeric composition. The polymerization syrup employed in formulating an acrylic-based particulate filled polymeric composition consist essentially of from about 300 to about 1,000 parts by volume of an acrylic monomer, from about 0.01 to about 1 part by volume of peroxide-free oxygen donator, from about 0.5 to about 5 parts by volume of a mercaptan, and from about 0.3 to about 40 parts by volume of a crosslinking agent compatible with the acrylic monomer.
