“INSTANTANEOUS IN SITU HIGH ORIENTATION” TOUGHENED MODEL OF PPO/SEBS-G-MAH BLENDS

FENG Wei MAO Lixin WU Dezhen LI Qifang LI Hangquan JIN Riguang (College of Materials Science and Engineering, Beijing University of Chemical Technology,Beijing 100029)  
For PPO/SEBS-g-MAH (Kraton FG 1901) blends with network morphology, “In- stantaneous in siam high orientation”, toughened model was proposed based on the fracture surfaces and microstructural deformation process. According to this model, the impact fracture of PPO/SEBS- g-MAH blends was initiated from the micro-cavities inside the elastomer and matrix, shear bands were subsequently induced by the micro-cavities resulting in a high orientation of the network structure, during which orientation molecular bunches were formed and a great amount of energy was consumed.
