PVC/CPE and PVC/EVA-G-VC blends were studied by fiiling Rigkl Organic Filiers(ROF).The results showed that a small amount of rigid polymer not only increased impact strength of PV C blends obviously
but also improved tensile modulus of those blends effectively
and had characteristics of non-elastomer toughened polymers. The effects of materled and processing condi-tions on mechanicai propertics of ternary bicnds were discussing.
