Abstract
An acrylic resin having an intrinsic viscosity [.eta.] of about 0.028 to about 0.117 l/g and a weight-average molecular weight to number-average molecular weight ratio (Mw/Mn), measured by gel permeation chromatography of about 2.3 to about 6.0, said resin comprising the polymerization product of (1) about 50 to 100 wt. % of methyl methacrylate and (2) 0 to about 50 wt. % of at least one monomer selected from the group consisting of acrylic ester monomer and methacrylic ester monomer, said acrylic ester monomer comprising the reaction product of an alkyl alcohol having 1 to 8 carbon atoms and acrylic acid and said methacrylic ester comprising the reaction product of an alkyl alcohol having 2 to 12 carbon atoms and methacrylic acid.
