## Abstract Tensile and compressive properties of polystyrene bead (PSB) foams at room temperature for strain rates from 10^β3^ to 10^5^ min^β1^ can be represented as nearly linearly increasing functions of modulus or stress versus the logarithm of the strain rate. The shear modulus and tensile dat

The diffusion coefficient of ethanol and of n-pentane in PTMSP, at 27ΠC, was measured as a function of concentration up to a penetrant content of about 12% by weight, for polymer samples obtained through different processes; differential sorptions and desorptions with vapor phases were considered.
