Control of the structure and properties of polyarylates during processing

Properties of Blends of High-Impact Polystyrene HIPS-0801 with High-Density Polyethylene

“…At the very least it is possible to speak of the fact that, in the presence of 5 wt.% HDPE, there is a tendency for an improvement in its tensile and impact properties. Taking into account the scientific positions formulated by the Akutin school [1][2][3][4], it can be assumed that the established specific values of these properties are a consequence of the possibility of the formation during the processing of the HIPS modified with small additions of HDPE of more ordered polymeric structures. The different breakdowns of the polymer structure of HIPS encountered in the form of regions with increased free volume may also have a positive effect on the impact strength, since it is well known that a hole drilled on the path of a crack in brittle material is capable of slowing down its development considerably.…”

“…A promising and rapidly developing direction in the area of creating new polymeric materials meeting specific prescribed service and process requirements is the modification of known polymers with small additions of substances of different chemical nature. The scientific principles of this direction, developed earlier in studies by colleagues of the Department of Technology for the Processing of Plastics of the D. I. Mendeleev Moscow Chemico-Technological Institute (now the Russian Chemico-Technological Institute) under the leadership of M. S. Akutin [1][2][3][4], are also of great interest in terms of creating polymer-polymer composites based on largetonnage polymeric materials. Among these materials, of specific practical interest are high-impact polystyrenesproducts of the graft copolymerisation of styrene with butadiene or butadiene-styrene rubber.…”
