Abstract

Phosphorus and boron containing polyethylene glycol esters (PB-PEG) toughening agent was synthesized by the esterification of phosphorus pentaoxide (P2O5), boric acid and polyethylene glycol (PEG). Phenolic foams toughened with PB-PEG were prepared. It is found that the flexural and compression strength of the foams increases with the addition of PB-PEG. Optical images of the foams show that the addition of the toughening agents can make the cells uniform and regular. LOI results indicate that the incorporation of PB-PEG has positive effect on the fire resistance of the foams. Moreover, pulverization ratio of the toughened foams was reduced.
