Contents: Comparative behavior of modified and unmodified glass-reinforced polypropylene during aging in air (135°C) and in antifreeze (115°C) with the exposure up to 80 days was investigated. Mechanical properties (tensile strength, flexural strength, impact strength) and melt flow were measured for original and aged samples. According to Hg-porosimetry data, unmodified composite has a loose macroporous structure. Aging leads to progressive phase separation. On the contrary, original modified composite is characterized by a dense structure; aging leads to the structure compacting, pore size decreases. Unmodified composite displays a drastic decrease of mechanical properties after 10 days of heating. Modified thermostabilized glass-filled polypropylene holds its thermooxidative stability during aging in air and in antifreeze, its molecular weight characteristics remain practically constant.
