The fire causes a great loss to the people’s lives and properties every year because the textile lacks of the flame retardant property, so the development of the flame retardant textile finishing agent plays a very important role in the textile finishing. With the improvement of the finishing technology, multifunction is the trend of the textile finishing agent, in which flame retardant combined with water and oil repellency is desirable. The organic flame retardant which containing phosphorus, nitrogen and silicon are becoming the focus of research due to its excellent flame retardant property and low toxicity. The finishing agent containing short fluoroalkyl chain (CnF2n+1, n≤6) or perfluoropolyether are easier to degrade and less bioaccumulation, are thought to be the substitution of the agent containing long perfluoroalkyl chain (CnF2n+1, n≥8).In this thesis, firstly, starting from phosphorus oxychloride, neopentyl glycol, dibromoneopentyl glycol, N-hydroxyethyl piperazine, methacryloyl chloride, propargyl alcohol and isopropylamine, the monomers 1 and 2 which containing phosphorus and nitrogen were synthesized respectively. In addition, compound 6 was synthesized from triblock perfluoropolyether alcohol and methacryloyl chloride. The monomers 1 and 2 were copolymerized with other acrylate monomers by emulsion polymerization to provide copolymers PA1 and PA2 respectively. The monomers 1 and 2 were copolymerized with fluorine-containing monomers to provide copolymers PFPA1, PFPA2 and PFOPA1 respectively. The polymers were applied on cotton fabric, the limited oxygen index(LOI) of the fabric treated with PA1, PA2, PFPA1, PFPA2 and PFOPA1 were 26.3%,20.5%,23.4%,19.5% and 22.8%. The contact angle for water of the fabrics treated with PFPA1, PFPA2, PFOPA1 were 141°,140°and 142°respectively. The oil repellent property of the fabrics treated with PFPA1 and PFOPA1 were grade 1 and 5 respectively. Secondly, starting from phosphorus oxychloride, pentaerythritol, neovaricaine, methacryloyl chloride and hydroxyethyl acrylate, the monomers 3 and 4 which containing the chemical structure of caged bicyclic phosphate were synthesized. These two monomers were copolymerized with other acrylate monomers by emulsion polymerization to provide copolymers PA3 and PA4 respectively, and were copolymerized with fluorine-containing monomer and other acrylate monomers to provide copolymers PFPA3 and PFPA4, the compatibility of the two monomers copolymerized with fluorine-containing monomers were studied. The LOI of the fabrics treated with PA3, PA4, PFPA3 and PFPA4 were 22.2%,22.0%,20.3% and 20.8%, but the fabrics treated with polymers PFPA3 and PFPA4 did not show water and oil repellent properties.Thirdly, starting from 3,3,3-trifluoropropyl trimethoxysilane,3-chloropropyl trichlorosilane, propargyl alcohol and methacryloyl chloride, the monomer 5 which containing POSS structure was synthesized. This monomer was copolymerized with other acrylate monomers by emulsion polymerization to provide copolymer PA5, and copolymerized with fluorine-containing monomer and other acrylate monomers by emulsion polymerization to provide copolymer PFPA5. The polymers were applied to cotton fabric finishing, the LOI of the fabric treated with PA5 was 19%, and for fabric treated with PFPA5 was 18.4%. The contact angle for water of the fabric treated with PFPA5 was 130°.
