Non-halogenated monomers that can be polymerized into flame retardant polymers, and processes to produce the monomers and polymers is provided. In a simplest aspect, there is provided a monomer composition that can comprise a) a group derived from one of a (meth)acrylic acid, (meth)acrylamide, or vinylbenzene, b) a polyphosphate moiety, and c) an amine species. In the monomer composition, the ethylenically unsaturated monomer of (a) is covalently bonded directly or through a linking group to the moiety of b), forming a precursor monomer unit. The amine species of c) is in complex with the precursor monomer unit. The polymer can be a homopolymer of the monomer composition, or a copolymer of the monomer composition having varying a), b) and c). In one embodiment, the polymer can additionally comprise ethylenically unsaturated monomers not covalently bonded to a polyphosphate moiety and/or can be cross-linked with a cross-linking agent such as resorcinol.
提供了可聚合成阻燃聚合物的非卤化单体,以及生产单体和聚合物的工艺。在最简单的方面,提供了一种单体组合物,该单体组合物可包含 a) 由(甲基)丙烯酸、(甲基)丙烯酰胺或乙烯基苯之一衍生的基团,b) 聚磷酸盐分子,以及 c) 一种胺类。在单体组合物中,(a) 的乙烯基不饱和单体直接或通过连接基团与 b) 的分子共价键合,形成前体单体单元。c) 的胺类与前体单体单元复合。聚合物可以是单体组合物的均聚物,也可以是具有不同 a)、b)和 c)的单体组合物的共聚物。在一个实施方案中,聚合物还可以包括未与聚磷酸盐分子共价键合的乙烯不饱和单体,和/或可以与间苯二酚等交联剂交联。
