POLYISOBUTYLENE-BASED THERMOPLASTIC BIORUBBERS

Rubber Chemistry and Technology, 2010
Abstract Linear triblock poly(styrene-b-isobutylene-b-styrene) (SIBS), the first representative of polyisobutylene (PIB)-based biomaterials, is approved by the Food and Drug Administration for use in the Taxus® Drug Eluting stent. SIBS and the new generation of dendritic or arborescent D_SIBS are self-assembling thermoplastic elastomers (TPEs),

Enthalpy-Driven Polyisobutylene Depolymerization

Macromolecules, 2019
Polyisobutylene (PIB) oligomers containing terminal alkene groups depolymerize rapidly at room temperature in the presence of trifluoromethanesulfonic acid and an arene solvent like benzene.

Anomalous Flow of Polyisobutylene

Rubber Chemistry and Technology, 1967
Abstract This work began as a study of shear degradation in a polymer melt subjected to a uniform shear field. A new type of biconical rotor rheometer was designed and constructed for it. Early in the investigation, however, phenomena were observed which led our efforts away from the original objectives. Viscosity data on a polyisobutylene melt

Butyl Rubber and Polyisobutylene

1989
Butyl rubber and polyisobutylene are elastomeric polymers1 used quite widely in adhesives and sealants both as primary elastomeric binders and as tackifiers and modifiers. The principal difference between these polymers is that butyl is a copolymer of isobutylene with a minor amount of isoprene, which introduces unsaturation, while polyisobutylene is a

Polyisobutylene based designed polymers

Macromolecular Symposia, 1996
AbstractThe field of cationic polymerization has moved center stage with the recent discovery of living polymerization that lead to the design of polymers with controlled molecular architecture. This report will provide a brief introduction of living cationic polymerization of isobutylene (IB) by tertiary ethers, and new cationic initiating systems ...
