Abstract

The graft copolymerization of acrylic acid onto acrylonitrile‐butadiene‐styrene terpolymer (ABS), has been initiated by the use of both benzoyl peroxide and azobisisobutyronitrile. Addition occurs in the butadiene region of the polymer, either by the loss of a vinylic hydrogen and subsequent radical formation and addition of monomer or by addition to the double bond. The amount of acrylic acid which may be added is dependent upon the time and temperature of the reaction and the concentration of monomer and initiator. Thermal analysis of the grafted samples show that the residue is less than that expected based upon the composition of the copolymer; similar results have been previously obtained for acrylic acid grafted by another technique.
