Materials of commercial significance in the rubber industry are usually multi-component systems composed of several elastomers and various fillers. Elucidating the complex morphology that can arise from blending and understanding how this affects the

The interfacial properties of a homopolymer (polybutadiene (PB)) and a terpolymer (brominated poly(isobutylene- co - p -methylstyrene) (BIMS)) are reported. Neutron reflectivity was used to study the interfacial structure. The results were complement

The effects of carbon black and pyrogeneous silica fillers on the interfacial properties of a homopolymer (polybutadiene, (PB)) and a terpolymer (brominated poly(isobutylene-co-p-methylstyrene), (BIMS)) are reported. Neutron reflectivity (NR) was use

The crosslinking of partially brominated poly(isobutylene-co-4-methylstyrene) elastomer 1 by phenolic resin crosslinkers was investigated. The curing was modeled using small molecule analogs of the elastomer and the phenolic resin. In order to mimic

The analysis of chemical and physical network heterogeneities has been carried out for synthetic isobutylene-based elastomers using 1H spin echo NMR imaging. Spatial homogeneity was compared for isobutylene−p-methylstyrene−p-bromomethylstyrene (P

A number of isobutylene-based graft copolymers with different compositions are compared to several commercial thermoplastic block copolymers, such as SIS, SBS and SEBS, in terms of morphology and viscoelasticity. The backbone of these graft copolymer

Blends of elastomers are widely used throughout the rubber industry. Blends are frequently used to get a balance of properties which cannot be achieved through the use of a single elastomer. For example, poly(isobutylene-co-4-bromomethylstyrene) can

The analytical technique of contact angle analysis has been used both to monitor organic transformations on the surfaces of fluoropolymer films and also to help correlate surface structure with wettability. This paper describes the preparation and ch

The atomic force microscope in the shear force modulation microscopy (SMFM) mode has been used to characterize the surface modulus and cross-link density of elastomer thin films, where standard rheological methods cannot be applied. Brominated poly(i

To obviate the destructive interaction of highly reactive metallocene catalysts with classical silica-based supports while retaining the advantage of supported catalysts, a noninteracting polystyrene support was developed. Supported catalysts for the
