Abstract-This paper dealt with the synthesis and characterization of the polymeric product by the reaction of the water-soluble poly (vinyl alcohol)[PVA] nonwoven fabrics and the phosphoryl chloride (POCl3), which has been applied to prepare water-proofing materials or intermediates for increasing water-proofing or fire-proofing ability of commercially available water-soluble PVA support layer. POCl3 was reacted with PVA nonwoven fabrics under non-aqueous condition, and their reactivity, and chemical structure were checked and discussed. PVA was reacted with POCl3 under the reaction condition of 1:1, or 1:2 mole ratios at 70, 80 and 90℃, and the reaction products were further hydrolyzed. The structure of the resulting products from water soluble PVA nonwoven fabrics reacted with POCl3 were identified by FT-IR or X-ray fluorescence spectrophotometer, and they indicated the PVA polymer chains to have phosphorous and chlorine moieties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
