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: (a) from about 300 to about 1000 parts per volume of an acrylic monomer represented by the formula <IMAGE> wherein R is an alkyl moiety containing 1 to about 18 carbon atoms; (b) from about 0.1 to about 1 parts by volume of 2,2-bis(allyl-oxymethyl)-butan-1-ol; (c) from about 0.5 to about 5 parts by volume of a mercaptan; and (d) from about 0.3 to about 40 parts by volume of a crosslinking agent compatible with the acrylic monomer. The polymerization syrup can further contain from about 1 to about 100 parts by volume of a polycarbonate compound.
