Two series of polyesters have been synthesized, one based on terephthalic acid and the other based on 2,6-naphthalene-dicarboxylic acid. Three diols were used: ethylene glycol, 1,4-butanediol and 1,10-decanediol. The polymers have been characterized

Spacecraft flying in a low Earth orbit environment require thermal blankets to provide protection from direct solar heat from the sun. Fluorinated ethylene propylene copolymer is one of the major components of these thermal blankets. In this study, t

Measurements of molecular weights, soluble fractions and examination of NMR spectra of bisphenol-A polysulfone, after gamma irradiation in vacuum at 150 degrees C were used to elucidate the mechanism of crosslinking. Excellent agreement was obtained

It has been shown in a previous article that melt blending of low levels of commercial poly (dimethyl siloxane) (PDMS) fluid with commercial thermoplastic polyurethanes has a significant positive impact on the coefficient of friction (CoF) and on the

A dry sand–rubber wheel abrasion test was used to investigate the wear behaviour of polyurethanes. The dry sand–rubber wheel abrasion test (DSRW test) is an approved ASTM test designed primarily for testing metals, therefore, in this study the se

The polymerisation of diethylene glycolbis-allyl carbonate to high conversion was investigated by ESR, FTIR and DMA techniques. The ESR spectrum was simulated using a two line, a three line and a broad line spectral component. These spectral componen
