    摘要: Compositions of polyphosphazene-containing polymers and methods of preparation thereof are provided. The disclosed compositions encompass telechelic functionalized polyphosphazenes and a variety of block and graft polyphosphazene-polystyrene, polyphosphazene-polysiloxane, and polyphosphazene-ROMP of norbornene copolymers. Methods for the preparation of such compositions generally involve generation of a polydichlorophosphazene species, attachment of a function group to the resultant polyphosphazene compound, and coupling the functionalized polyphosphazene with a corresponding organic or inorganic polymers or polymerizing the functionalized polyphosphazene with corresponding organic molecules.

    摘要: 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.

    摘要: Disclosed are low-tack, hydrophobic, high refractive index, acrylic materials. These materials, especially useful as intraocular lens materials, contain one or more aryl acrylic hydrophobic monomers as principal device-forming monomers, a tack-reducing macromer additive and a glistening-reducing additive. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other implantable ophthalmic devices.
