چكيده فارسي :
A series of semi-interpenetrating polymer networks (SIPN) based on bisphenol A epoxy resin and thermoplastic polyurethane was prepared by solution blending. Epoxidized soybean oil (ESO) was used to modify the IPNs in this study. Polymer/ESO ratio of the system was changed from 100/0 to 70/30. The Effect of soybean oil content on morphology and dynamic mechanical properties of the system was studied systematically. Results revealed that the Epoxy/Polyurethane system with soibean oil showed lower glass transition temperature, lower crosslink density and higher toughness.
