Patent number: 10174140Abstract: 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.Type: GrantFiled: May 23, 2014Date of Patent: January 8, 2019Assignee: LUBRIZOL ADVANCED MATERIALS, INC.Inventors: John Ta-Yuan Lai, Ti Chou
