Maleic Anhydride-Grafted Isotactic Polybutene-1 and Modified Polyamide 6.

Maleic anhydride (MAH)⁻divinyl benzene (DVB) multi-monomer melt-grafting onto isotactic polybutene-1 (iPB-1) was carried out in a torque rheometer. The effects of dicumyl peroxide (DCP), MAH, and DVB concentrations, and temperature, on the reaction, were investigated. The optimized conditions were 170 °C, DVB/MAH = 4:6 (mass ratio).
