摘要

1455783 Acrylic and methacrylic acid esters and amides containing phosphorus SCOTT PAPER CO 11 Jan 1974 [19 Jan 1973] 01450/74 Heading C2P Novel compounds of formula where R 1 is H or CH 3 ; R 2 is optionally substituted C 1 -C 3 alkylene; R 3 , R 4 , R 5 and R 6 are CH 3 or C 2 H 5 ; and X and Y are each -O- or -NH- may be prepared by reacting phosphorus oxychloride with compounds of formula R 3 -NH-R 4 and R 5 -NH-R 6 . Intermediates of formula may be isolated when reaction with the amine(s) is carried out first. The compounds of Formula I may be graft copolymerized on cellulosic fibres to give flame retarded fibres.
