Abstract:
There is described a co-polymerisable phosphorus containing polymer precursor which comprises: a) a polymerisable unsaturated bond; b) a oxycarbonyl or iminocarbony group; and c) a free hydroxy group or a functional group obtainable by reaction of a free hydroxy group with a suitable electrophile; and d) a terminal phosphorus and oxygen containing group located at the end of a carbon chain and comprising at least one group selected from: hydroxy phosphorus and an optionally substituted hydrocarbyl group attached to a phosphorus atom through an oxy group; where the polymer precursor: is substantially free of halo comprising species; has a molecular weight (Mn if a polymer) of from about 200 to about 5,000 daltons; and optionally, has a Hoppler viscosity measured at 25° C. of less than about 14,000 mPa.s. These polymer precursors are obtainable as the product of a reaction between an optionally substituted terminal phosphate or H-phosphonate ester and compound comprising at least one oxiranyl, preferably epoxy, ring adjacent an alkylidenylcarbonyloxy group. The polymer precursors can be copolymerised with other monomers to produce copolymers such as phosphorus containing polyurethanes which for example have use as flame retardants, anti-corrosives, pigment dispersants and/or adhesion promoters.
