ABSTRACT:
Styrene-terminated polyethers of polyphenols may be used as components in a laminate when coated on a reinforcement or substrate. The poly(vinyl benzyl ether) may be prepared by reacting a bisphenol with an alpha,omega-diahlosubstituted alkane and thereafter reacting the resultant product with vinyl benzyl chloride. The laminates which are prepared from these compounds may be employed in electric or electronic circuit boards and will possess desirable electrical and thermal properties as exemplified by a moderate-to-high glass transition temperature and a low dielectric constant.
