Radical polymerizations of a styrene dimer, 2,4-diphenyl-l-butene, as a thermal degradation product of polystyrene for chemical recycling, were investigated under variable reaction conditions: benzoyl peroxide (BPO)-initiated radical polymerization, atom transfer radical polymerization (ATRP), stable free radical polymerization (SFRP), and reversible addition-fragmentation chain transfer (RAFT) polymerization conditions. The homopolymerizations of SD hardly proceeded probably because of steric hindrance of bulky α-substituent of SD. Radical copolymerizations of SD with styrene produced relatively high-molecular-weight-copolymers [the number-average-molecular-weights (M n ) = 4030∼14500] containing of SD about 30 mol%. The glass transition temperature (T g ) of these copolymers was ∼130°C, much higher than that of polystyrene. [ABSTRACT FROM AUTHOR]
