phosphorus trichloride with tert-butanol and fluoroalcohols gave bis(fluoroalkyl) phosphites (RFO)2P(O)H in 42–89% yield, where RF=HCF2CH2, H(CF2)2CH2, H(CF2)4CH2, CF3CH2, C2F5CH2, C3F7CH2, (CF3)2CH, (FCH2)2CH, CF3(CH3)2C, (CF3)2CH3C, CF3CH2CH2, C4F9CH2CH2 and C6F13CH2CH2. Treatment of these with chlorine in dichloromethane gave the bis(fluoroalkyl) phosphorochloridates (RFO)2P(O)Cl in 49–96% yield. The chloridate

Ten fluoromonomers of structure (RFO)2P(O)OCH2CH2OC(O)CRCH2 were made in 30–64% yield by treating the chloridates (RFO)2P(O)Cl with HOCH2CH2OC(O)CRCH2 in chloroform in the presence of triethylamine [RF=CF3CH2, C2F5CH2, C3F7CH2, C4F9CH2, C4F9CH2CH2 or C6F13CH2CH2; R H or Me]. The chloromonomer (CCl3CH2O)2P(O)OCH2CH2OC(O)CHCH2 was obtained analogously in 29% yield. Polymerisation of the acrylate
