Abstract

PURPOSE: To obtain an acrylic resin having improved solvent resistance, moldability, transparency, and heat distortion resistance, comprising methyl methacrylate and a higher alkyl methacrylate.
CONSTITUTION: A monomer mixture comprising (A) 40W95 wt.% of methyl methacrylate, (B) 5W50 wt.% of a higher alkyl methacrylate of formula CH2C (CH3) COOR [R is 4W20C straight-chain alkyl or 5W20C brabched chain alkyl group] and, if necessary, (C) 10 wt.% or less of an alkyl acrylate is polymerized to give a solvent-resistant acrylic resin. A ≤3C alkyl group in the component (B) increases the glass transition temperature of the copolymer and further the crack initiation with good solvents. If the carbon number of the group is too large, the rate of crack initiation is increased. A 4W20C, preferably 6W12C alkyl group is therefore selected.
