3 - epoxy propoxy ) propyl )disiloxane (TEDS) was synthesized and used as modifier for epoxy reSin. Basedon the studies on the curing kinetics of TEDS/ DDM system as well as model rcasnon of TEDS/di - n- butylamine
the first order kinetic was proposed for TEDS.Besides
the dynamic mechanical behavior
impact strength and the morphology ofDGEBA/DDM system modified with TEDS were studied. Results showed thatthe impact strength of the modified system was found to be enhanced with the increase of TEDS content
whereas the glass transition temperature (Tg) was de-creased linearly. SEM observation of the fracture surface of the impact specimen al-so showed that as the increase of the modifier content the toughed fracture charac-ters were obviously appeared.
