Transparent thermoplastic resin with electron beam cross‐linking

Abstract

The mechanical, thermal and optical properties of a transparent thermoplastic resin which is based on noncrystalline nylon with cross-linking agents were improved by electron beam (EB) irradiation cross-linking. When the EB irradiation power was increased, the yield stress improved by 34% and the glass transformation temperature increased from 116 to 1658C. Transformation from the brittle to the ductile state was observed by the dependence of a strange elastic module on the temperature and EB irradiation power. Above the glass transformation temperature, an optical element produced using this resin could maintain its shape. The birefringence decreased when the EB irradiation power was increased. The decrease of the birefringence was dependent on the initial birefringence value before EB cross-linking. The molecular orientation was relaxed by EB cross-linking. POLYM. ENG. SCI.,

Antistatic surface properties of plastics using donor-accepter molecular compounding antistatic agent

“…In recent years, metal and glass materials are being replaced with plastic materials in various industrial applications owing to amazing improvement of processing accuracy of plastic materials, and a lot of studies have been reported with regard to the development and processing of high performance plastic materials [1][2][3]. In the field of optical communication, the use of transparent plastic materials as optical connection components is being actively developed [4,5], and, demand for transparent plastic materials is expected to increase in future.…”
