Abstract
Vinylbenzyl ethers of polyphenolics such as bisphenol A and novolac resins comprise a new class of curable resins which have marked advantages over comparable types of resins. They have the greater ease of free-radical curing compared to epoxy resins. The cured resins have greater stability than polyester resins because of the lack of hydrolyzable groups, and they have high heat distortion temperatures. Additionally, the resins produce solutions of low viscosity with comonomers such as styrene.
