20140296396 | NON-HALOGEN FLAME RETARDANT POLYMERS - 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. | 10-02-2014 |

20150376325 | POLYMERS MADE FROM TELECHELIC N-ALKYLATED POLYAMIDES - This invention relates to polymers made from low molecular weight polyamide oligomers and telechelic polyamides (including copolymers) containing N-alkylated amide groups in the backbone structure. The described telechelic polyamides are used as the soft segment in the described TPU. These telechelic polyamides are unique in that they have an unexpectedly low glass-transition (desirably 30 degrees C. or lower) which makes them suitable for further reaction and polymerization, allowing for the formation of the described TPU. The resulting TPU can provide improved hydrolytic, oxidative and/or thermal stability as well as improved adhesion to other materials, especially polar materials. | 12-31-2015 |
