An acrylic/lactam monomer based polymeric resin is provided which has excellent weatherability, outstanding transparency and optical clarity, improved heath and solvent resistance, as well as improved impact strength. The acrylic/lactam monomer based polymeric resin is formulated by the catalytic activation at ambient temperature of a polymerization syrup which contains from about 300 to about 2970 parts by volume of an acrylic monomer, from about 30 to about 2700 parts by volume of a lactam monomer, from about 0.3 parts to about 40 parts by volume of a mercaptan chain transfer agent and from about 0.3 to about 40 parts by volume of a crosslinking agent capable of crosslinking the acrylic monomer and the lactam monomer. To prevent further polymerization of the polymeric constituents of the polymerization syrup, as well as to enhance the shelf life of the polymerization syrup, an effective amount of a polymerization inhibitor and an ultraviolet light stabilizer are incorporated into the polymerization syrup. The crosslinking of the acrylic monomer and the lactam monomer is carried out at ambient temperature and atmospheric pressure.

An acrylic resin is provided which has excellent weatherability, outstanding transparency and improved heat and solvent resistance, as well as improved impact strength. The acrylic resin comprises an intimate blend of a polymerization syrup and a catalytic amount of a polymerization catalyst capable of effecting polymerization of the syrup. The polymerization syrup, which has an improved shelf life and can be stored at ambient temperature and atmospheric pressure, consists essentially of:

Acrylic/carbonate resins are provided which have excellent weatherability, outstanding transparency and improved heat and solvent resistance, as well as improved impact strength. The acrylic/carbonate resins comprise an intimate blend of a polymerization syrup and a catalytic amount of a polymerization catalyst capable of effecting polymerization of the syrup. The polymerization syrup, which has an improved shelf life and can be stored at ambient temperature and atmospheric pressure, consists essentially of:

Acrylic/carbonate resin compositions

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.
