    • 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 DEG C of less than about 14,000 mPa.s. These polymer precursors are obtainable as the product of a reaction between an optionally subsitituted 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.
    • 描述了可共聚的含磷聚合物前体,其包含:a)可聚合的不饱和键; b)氧羰基或亚氨基羰基; 和c)游离羟基或通过游离羟基与合适的亲电体反应获得的官能团; 和d)位于碳链末端的末端含磷和氧的基团,并且包含至少一个选自羟基磷和通过氧基连接到磷原子的任选取代的烃基的基团; 其中聚合物前体:基本上不含有包含卤素的物质; 具有约200至约5,000道尔顿的分子量(如果聚合物为Mn) 并且任选地,在25℃下测得的Hoppler粘度小于约14,000mPa·s。 这些聚合物前体可作为任选取代的末端磷酸酯或H-膦酸酯与包含至少一个环烷氧基的化合物,优选环氧基,邻近亚烷基羰基氧基的化合物的产物获得。 聚合物前体可以与其它单体共聚以产生共聚物,例如含磷聚氨酯,例如用作阻燃剂,抗腐蚀剂,颜料分散剂和/或粘合促进剂。
