Magnetic field effect on the photocrosslinking of a butadiene-styrene copolymer modified by benzoyl or phenylacetyl groups

Summary

A butadiene-styrene copolymer was partially modified by Friedel-Crafts reaction of phenyl groups with benzoyl chloride or phenylacetyl chloride. The resulting benzoylphenyl and phenylacetylphenyl groups served as photosensitizers for a subsequent crosslinking by u.v. irradiation. The extent of crosslinking was measured by sol/gel analysis. Crosslinking was carried out without magnetic field and with magnetic field of flux density 1.0 Tesla. The experiments with magnetic field yielded about 5% less soluble polymer, corresponding to a higher crosslink degree. The data were evaluated by statistical methods.
