The performance and radiation‐induced cross‐linking of polycaprolactone (PCL) in the presence of vinyltrimethoxysilane (VTMS) have been investigated. Radiation‐induced cross‐linking of PCL in the presence of VTMS followed the Charlesby–Pinner equation, and VTMS promoted the radiation‐induced cross‐linking of PCL. As the concentration of VTMS increased, the gelation dose and the ratio of degradation to cross‐linking ( p 0 / q 0 ) decreased and the efficiency of radiation‐induced cross‐linking increased. Differential scanning calorimetry analyses showed differences between the first and second scans. Glass‐transition temperature ( T g ) and mechanical properties of the polymers increased. Radiation‐induced cross‐linking of PCL in the presence of VTMS was found to retard hydrolytic degradation greatly. POLYM. ENG. SCI., 2011. © 2010 Society of Plastics Engineers
