AbstractLow molecular weight copolymers of (1) acrylic acid esters or methacrylic acid esters of alcohols such as methanol with (2) esters of bicyclic alcohols such as isobornyl alcohol and unsaturated acids such as methacrylic acid, as contrasted with high molecular weight copolymers of such monomers (1) and (2) (see U.S. Pat. No. 3,485,775) and as contrasted to other acrylic polymers, are found to be exceptional in compatibility with practically all types of hard coating resins, and to lower the flow temperature of the mixture when using powder coating methods such as an electrostatic spray or a fluidized bed, electrostatic or not, as compared with the use of the hard coating resin alone.
