Chain structure, phase morphology, and toughness relationships in polymers and blends

“…Figure 7 shows indeed such a correlation. The T~ values are taken or estimated from various sources (2,38,43). It can be seen that the T~ value increases with increasing matrix ductility (decreasing C, value), as expected.…”

Solution maleation of EPDM and blending of acetal copolymer with rubber using maleated EPDM as compatibilizer

“…content of bond MAH in the products is quite low, But they fail in a brittle manner when impacted. usually below 1.6 wt %, due to the limited solubil-In order to increase the toughness of POM, blendity of MAH in the rubber and the high volatility ing of POM with thermoplastic polyurethane has of MAH at high temperature, while in the solution been reported by Flexman, 6 Chiang and Lo, 7 and method most works were concerned with the co-Chiang and Huang. 8 However, almost no work polymer and the bond MAH content only reached concerning the blending of POM with rubber for 7 wt %, 2 so as to avoid gel formation.…”
