Methods of measurement and interpretation of results,go it was discovered that the fracture resistance of polystyrene (PS) was increased by adding some amounts of rubber. This discovery became of paramount interest in tailoring the microstructure and the related property profile [1] and led to the commercialization of the ever-broadening family of high impact thermoplastics.作者: 積習(xí)已深 時(shí)間: 2025-3-25 23:46
