In situ intercalative polymerization is an environmentally-friendly process to produce polymer-clay nanocomposites with good clay dispersion. In this work, quaternary ammonium salts with tertiary amine groups were synthesized to modify clay as cataly

Most developments of high performance polyurethane foam systems for manufacturing sport shoe midsole wedges have concentrated on reducing the density while maintaining physical properties. In the drive to reduce the density of the midsole material it

The largest use of polyurethane (PU) is as closed cell rigid foams for thermal insulation. One problem is loss of blowing gases, which leads to slow increase in thermal conductivity. PU composites with plate-like nanofillers create a diffusion barrie

Polyurethanes were prepared from pure 4,4′-diphenylmethane diisocyanate (MDI), 1,4-butane diol (BDO) or 1,2-ethane diol (EDO) and α,ω-hydroxyl poly(propylene oxide) (PPO) by reaction injection moulding (RIM). Hard segment (MDI + BDO or EDO) level

Reaction injection molding or RIM is the high speed production of polymer parts directly from low viscosity reactants injected into a mold. In contrast to thermoplastic injection molding, where the part solidified upon cooling, in RIM the shape is se

The development of heterogeneous structure during the polymerization of a polyurethane system using a polyether diol of Mn = 2000 as the soft segment and 4,4′-diphenylmethane disocyanate extended with 1,4-butanediol as the hard segment was monitore

We have shown that the adiabatic reactor method (A.R.M.) is useful to measure bulk polymerization kinetics. The choice of an adequate model is fundamental to represent the kinetics and for use in modeling and processing applications. The definitions
