An innovative nanoscale ZnO/polybutadiene rubber composite (ZBRC) was developed as a valid alternative to TiO2 particles or immobilized TiO2 for the mineralization of chlorinated hydrocarbons without difficulties in the recovery of nanoscale photocatalyst particles. A synergistic increase in the removal of 1,1,2-trichloroethylene (TCE) through the coupled reaction processes (i.e., sorption, pho...

Abstract In this study, the mechanical response of HTPB propellant grain under ultra-high loads is investigated. The low, intermediate and high strain rate uniaxial compression tastings (1.7×10 −4 ~3×10 3 s −1 ) hydroxyl terminated polybutadiene (HTPB) at room temperature were carried out by using universal testing machine split Hopkinson pressure bar (SHPB) system, respectively. tests cellular...

The average golfer and most professionals play with two-piece, three-piece, or four-piece layered golf balls. A typical two-layered golf ball is composed of a crosslinked rubber core (polybutadiene or polyurethane) and a rigid and glassy outer skin (poly(methacrylic acid) ionomer. A crosslinked rubber is an ideal thermodynamic material that recovers completely after extensive impact (rubber ela...

A simple but robust kinetic mathematical model to predict the mechanical/thermal behaviour of NR and highcis polybutadiene rubber blends is presented. The benchmark blend is a 70% NR with 30% high-cis polybutadiene blend vulcanized in presence of sulphur at 1 phr and single accelerants TBSS or DPG at concentrations equal to 1-0 and 0-1 respectively. Experimental rheometer curves are at disposal...

This work explores the effect of core-shell rubber (CSR) addition on cure reaction and resulting mechanical thermal properties a highly cross-linked network made from 4,4′- tetraglycidyl diamino diphenyl methane 3,3′-diamino sulphone. Up to 20 wt% CSR rubber, composed soft polybutadiene core hard poly methyl methacrylate (PMMA) shell was dispersed in epoxy/amine after found increase glass trans...

An efficient use of plasticizers in rubber compounds requires an understanding their miscibility behavior. Besides the chemical properties both and plasticizer, rigidity plasticizer plays important role for miscibility. The is investigated here using glass transition measured by differential scanning calorimetry broadband dielectric spectroscopy (BDS). Additionally, interfacial relaxation phase...

ABSTRACT Butadiene rubber (BR) is one of the most useful and second produced worldwide. Polymerization 1,3-butadiene (BD) a highly stereospecific reaction that offers wide variety BR with different microstructures influences fundamental properties rubber. Since first successful polymerization conjugated diene using Ziegler–Natta–based catalyst (TiCl4 or TiCl3 aluminum alkyls) in 1954, research ...
