Padma, A and Rao, RMVGK and Subramaniam, C (1994) Liquid elastomer for epoxy resin toughening. High Performance Polymers, 6 (1). pp. 63-70.Full text not available from this repository.
A liquid elastomer was synthesized using butyl acrylate, acrylic acid and acrylonitrile. The elastomer was characterized and used as a toughener for a high-functionality novolac epoxy resin to improve the impact strength of the resin castings. A chemical reaction between the epoxy resin used and the liquid elastomer synthesized was confirmed by infrared and dynamic mechanical analysis. Preliminary results indicated a 66% increase in impact strength of the castings with addition of 10% by weight of the elastomer. Scanning electron micrographs of the fractured surfaces showed the phase separation of the elastomer.
