THE PHYSICAL AND MECHANICAL CHARACTERISTICS RESEARCH OF POLYSTYRENE BY WATER ABSORPTION
Results of prolonged water absorption test of expandable polystyrene (EPS) and extruded polystyrene<i> </i> (XPS) are set forth in this paper. Dependence between the water absorpion of polystyrene <i> </i>slabs and the continuance of theirs seasoning in water was determine for the reason of experimental data. It was researched the influence of prolonged water absorption on the <i> </i>compression resistance when having 10% of linear strain, on the hardness by Shore's method of testing, on the quantity of linear growth or swelling. In this paper it is forth the polymer<i> </i> structure with strongly pronounced process of texture anisotropy progres in the issue of destruction
