Graft copolymerization of vinyl monomers onto polyamide-6 using radical initiation has been investigated. Two monomers were used: methacrylic acid (MAA) and acrylic acid (AA). The initiators selected included hydrogen peroxide ~02), benzoyl peroxide (BPO), and azobisisobutyronitrile (AIBN). The extent Or-graft copolymerization depends on the concentrations and identity of the initiator and monomer and the time and temperature of the reaction. The graft copolymers were not soluble in solvents which will dissolve the starting materials; definitive proof for the formation of the graft copolymers comes from infrared spectroscopy. Thermogravimetric analysis was performed on the graft copolymers, and it was found that the presence of the acid invariably accelerated the degradation of the polyamide.
