Abstract
An investigation was carried out into the sorption and diffusion of carbon dioxide in linear and branched polycarbonates by means of high-temperature, high-pressure gravimetry. Carbon dioxide-induced dilation of the polycarbonates and depression of Tg in the polycarbonates were also investigated and the plasticised Tgs obtained by dilation and solubility measurements compared with those obtained by differential scanning calorimetry. The discovery of a plasticisation-related densification phenomenon in the sub-glass transition temperature region is reported. 29 refs.

Abstract
Foamed blends of ethylene-styrene interpolymer and LDPE were subjected to a range of mechanical tests, including compressive impact testing, Instron compression and Poisson's ratio measurements, compressive creep measurements and compression set and recovery measurements. The data obtained were compared with those for EVA and the suitability of these foamed blends as replacements for EVA in the manufacture of soccer shin guards and midsoles for sports shoes was evaluated. 20 refs.

Abstract
The results are reported of an evaluation and comparison of alternative ignition sources for upholstery testing. The ignition sources evaluated included a multi-jet gas burner, a pyramid wood crib developed to simulate the burning behaviour of a 20g paper ball and a solvent/paper ignition source. Comparisons are made with the 20g paper ball and the No.5 Crib of BS5852 used to test upholstered seating and mattresses designated for use in public premises. Materials used for studying the ignitability of mattresses and upholstered seating composites are listed and the results reported. 5 refs.
