The successful copolymerization of α-methylstyrene with conjugated dienes such as 1,3-butadiene, isoprene and/or styrene was achieved by anionic solution polymerization in hexane using formulated catalyst systems at the ceiling temperature of α-met

Random or tapered solution styrene–butadiene copolymer (SSBR) is very difficult to prepare in an isothermal batch process without the use of polar modifiers because of the diverse reactivity ratios of the styrene and the butadiene in hydrocarbon so

Novel polymers that will contribute to a better combination of traction and tread wear in tire applications, which is historically difficult to achieve, have been developed. In this work, multiple viscoelastic polymers possessing multiple glass trans

The present work is to the syntheses and characterization of random, low vinyl copolymers containing styrene and isoprene (SIR’s). The content of these SIR’s ranged from 10% styrene/90% isoprene to 60% styrene/40% isoprene, and all were soluble i

We investigate the relaxation dynamics in the melt of entangled binary mixtures comprising a small fraction of short polybutadiene, polyisoprene and polystyrene chains in a high molecular weight (MW) matrix. In this way, we create model environments

Hydrocarbon elastomers bearing polar functional groups at their chain ends or at both chain ends can greatly reduce the hysteresis of a tire compound and thus improve rolling resistance and fuel economy. These functional elastomers can be easily prep

We explore filler reinforcement (i.e., increase of elastic modulus G‘ due to incorporation of fillers) and Payne effect (i.e., decrease of G‘ at large strain amplitudes) in terms of the matrix molecular weight, filler loading, and time scales use
