摘要：The syndioselective copolymerization of styrene (St) with five alkenyl functionalized styrenic monomers with the use of [(C5Me4SiMe3)Sc(CH2C6H4NMe2-o)(2)]/[Ph3C][B(C6F5)(4)] produced a new family of versatile syndiotactic polystyrene (sPS) materials with pendant alkenyl groups (C?C: 5-20 mol%, T-m: 220-250 degrees C). These styrenic monomers were divinylbenzene (FSt1), 4-isopropenylstyrene (FSt2), 4-(1-isopropylvinyl)styrene (FSt3), 4-(2-propenyl)styrene (FSt4) and 4-(2-methyl-2-propenyl)styrene (FSt5). Through thiol-ene click chemistry and epoxidation, new polar-group functionalized sPS materials were obtained efficiently, demonstrating that syndiotactic copolymers with pendant alkenyl groups can serve as reactive intermediates to produce various functional materials.
