    • A polymer composition comprising a polynorbonene backbone and pendant cyclotriphosphazene groups has been developed. The pendant cyclotriphosphazene group can have various substituents such as C1-C10 alkyl, C1-C10 haloalkyl, C3-C6 cycloalkyl, phenyl, substituted phenyl, aryl, —(CH2CH2OCH2CH2)nOCH3 in which n is a positive integer, aminoalkyl, alkoxyalkyl, phenoxyalkyl, aryloxyalkyl and amidoalkyl. The polynorbonene backbone can have substituents such as H, CH3, X which is a halo group, and C2-C6 alkyl, C3-C6 cycloalkyl, C2-C6 alkoxy, phenoxy, and aryloxy. In a preferred embodiment, the pendant triphosphazene group can have either —CH2CF3, phenyl, 4-ethylcarboxylatophenyl, —CH2CH3, or —CH2CH2OCH2CH2OCH3 while the polynorbonene backbone can have H and low alkyl groups. The polyphosphazene compositions can be prepared readily via ring-opening-metathesis-polymerization of an olefin having norbornene structure with pendant cyclotriphosphazene groups. The polyphosphazene compositions disclosed are useful as elastomers, optical materials, electrically conductive materials, biomedical materials, compatibilizing agents, surfactants, additives for coatings, and as flame retardants.
    • 已经开发了包含聚碳链烷骨架和侧链三磷腈基团的聚合物组合物。 侧环三膦腈基可以具有各种取代基,例如C1-C10烷基,C1-C10卤代烷基,C3-C6环烷基,苯基,取代的苯基,芳基, - (CH2CH2OCH2CH2)nOCH3,其中n是正整数,氨基烷基,烷氧基烷基,苯氧基烷基 ,芳氧基烷基和酰氨基烷基。 多亚碳烯骨架可以具有取代基,例如H,CH 3,X是卤素基团,和C 2 -C 6烷基,C 3 -C 6环烷基,C 2 -C 6烷氧基,苯氧基和芳氧基。 在一个优选的实施方案中,三膦酰基侧基可以具有-CH 2 CF 3,苯基,4-乙基羧基苯基,-CH 2 CH 3或-CH 2 CH 2 OCH 2 CH 2 OCH 3,而多亚氮烷骨架可具有H和低级烷基。 聚磷腈组合物可以通过具有降冰片烯结构的烯烃与侧链三环磷腈基团的开环 - 复分解聚合来容易地制备。 所公开的聚磷腈组合物可用作弹性体,光学材料,导电材料,生物医学材料,相容剂,表面活性剂,涂料用添加剂和阻燃剂。
