the functionalization of e-glass short fibers by treatment with chloromethyldimethylchlorosilane has been studied in various media both thermal and ftir analysis indicated that pyridine-catalyzed reaction in refluxing toluene produced surface immobilization of the -si(ch//2)//2ch//2-n** $plus$ c //5h//5 cl** $minus$ group by siloxane bonds, while refluxing in toluene alone failed to immobilize silane. this coating shows high thermal stability. in aqueous solution at ph 3.3, a deposit forms consisting of substantial amounts of silane (removed at 80 $degree$ c) together with a small quantity of the -si(ch//3)//2ch//2cl group coupled to the surface by siloxane bonds (removed only above 350 $degree$ c).
