Rheological and thermal degradation properties of hyperbranched polyisoprene prepared by anionic polymerization [PDF]
Royal Society Open Science, 2019 Hyperbranched polyisoprene was prepared by anionic copolymerization under high vacuum condition. Size exclusion chromatography was used to characterize the molecular weight and branching nature of these polymers.

Long time stress relaxation of amorphous networks under uniaxial tension: The Dynamic Constrained Junction Model [PDF]
, 2008 Poly-isoprene networks with different degrees of cross-linking and filler amount are studied under uniaxial stress relaxation. Time decay of stress obeys a stretched exponential form with a stretching parameter of 0.4 that is same for all independent ...
