Poly(ethylene oxide) (PEO) of molecular weight from 200,000 to 2,000,000 was crosslinked by exposure to ultraviolet radiation with a high-pressure 150 W mercury lamp. Photochemical crosslinking of PEO proceeds in the presence of photoinitiators such as benzophenone and acetophenone which act as a hy
Polyisobutylene can be crosslinked under irradiation as to be expected by either introducing radiation sensitive groups into its macromolecules or blending with a proper radiation crosslinkable polymer.
## Abstract Films of ethyleneโ__co__โoctene copolymer are irradiated in air after moulding between Mylarยฎ films with electron beam at different doses. To correlate the change in structure with properties, the irradiated and unirradiated samples are characterised by FTIR spectroscopy, swelling and m
