The Toughness of Phenolic Foams
Ih this paper, the study of using four toughening systems Composed of chlorinated polyethylene, polyvinyl chloride and nitrible butadiene rubber to modify phenolic foams was carried out. the toughening mechnisrn of toughness was demenstheted by using of iefrared spectrum from melecular lever. The result indicated that the toughening effect of phenolic foams was best when using the thermoplastic elastomer.
