Effect of Volume and Temperature on the Global and Segmental Dynamics in Polypropylene Glycol and 1,4-polyisoprene [PDF]

, 2004
Published dielectric relaxation measurements on polypropylene glycol and 1,4-polyisoprene are analyzed to determine the relative effect that thermal energy and volume have on the temperature dependence of the normal mode relaxation times, and compare ...

Synthesis and Evaluation of Novel Thermoplastic Elastomers via Anionic Polymerization of Bio‐Based α‐Methyl‐p‐Methylstyrene

Journal of Polymer Science, Volume 64, Issue 3, Page 743-751, 1 February 2026.
Bio‐based PAMMS‐PI‐PAMMS triblock copolymers prepared via sequential anionic polymerization display widely tunable tensile behavior. Variation of the block composition enables systematic control of strength and extensibility, offering a sustainable platform for thermoplastic elastomers. ABSTRACT In this study, we examined novel thermoplastic elastomers

Harnessing Colloidal Dispersion for Laccase‐Driven Enzymatic Depolymerization of Polystyrene

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Polystyrene (PS), long considered non‐degradable by biocatalytic pathways, can now be broken down under aqueous conditions using atmospheric air and a laccase–mediator system composed of a commercially available fungal enzyme and 1‐hydroxybenzotriazole as small organic mediator.

Effect of carbon black amounts on dynamic properties of natural rubber/trans-1,4-polyisoprene blends

Hecheng xiangjiao gongye
A series of rubber samples with hardness gradient were prepared by blending natural rubber with trans-1,4-polyisoprene and adjusting the amount of carbon black N 330. The physical and mechanical properties and dynamic mechanical properties of the blended

Automatic Coarse Graining of Polymers

, 2003
Several recently proposed semi--automatic and fully--automatic coarse--graining schemes for polymer simulations are discussed. All these techniques derive effective potentials for multi--atom units or super--atoms from atomistic simulations.

Protein‐polyisoprene rubber composites

Journal of Applied Polymer Science, 2017
ABSTRACTHydrolyzed proteins previously shown to aggregate in aqueous solution were compounded into synthetic polyisoprene rubber (IR). Modulus increases of up to 232% resulted from protein reinforcement of IR. Increased hydrogen bonding on amine groups and the presence of β‐sheets in the protein phase were observed via Fourier transform infrared (FTIR)

Properties of Vulcanized Polyisoprene Rubber Composites Filled with Opalized White Tuff and Precipitated Silica

The Scientific World Journal, 2014
Opalized white tuff (OWT) with 40 μm average particle size and 39.3 m2/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi).
