Method for preparing a hybrid organodisilanol and polymers thereof

This invention provides 1) novel reactive fluorinated compounds derived from a specified class of telomers or cotelomers of fluoroolefins; and 2) stable products and stable polymers thereof obtained by reaction or polycondensation of the novel reactive fluorinated compounds with specified classes of hydrogenated aliphatic, alicyclic, aromatic reactive compounds, telechelic oligomers and block polymers wherein said stable products and polymers contain hetero atoms such as oxygen, sulfur or nitrogen and are characterized by high thermal and chemical resistance.

Fluorinated compounds containing hetero atoms and polymers thereof

The invention is concerned with silicone copolymer containing terminal and/or pendant oxyalkylene styrene groups which are crosslinkable in the presence of a photoinitiator when exposed to UV radiation and their use in a compositions for coating substrates to provide substrates with anti-adhesive properties.

Photo-crosslinkable silicones and their use

A process is described for preparing blends of fluorocarbon plastomers such as vinylidene fluoride polymers with fluorosilicone elastomers to obtain materials having a unique combination of flexibility at low temperature and high mechanical strength. Vinylidene fluoride polymer is first exposed to radiation and then mixed with the fluorosilicone. Coagents such as diallylphtalate and triallylisocyanurate are also used to assist in grafting and compatibilizing the two polymers.

Blends based on fluorosilicone elastomers and vinylidene fluoride

This invention relates to fluorohydrocarbon polymers which are modified by the incorporation of substitiuents bearing a functional group such as vinyl, allyl, acrylate, alkoxysilane, amido, sulfonic acid salt, pyridine, carboxylic ester, and carboxylic salt. The functional groups may be further reacted to obtain branching, grafting, or crosslinking of the polymers. Copolymers of vinylidene fluoride and hexafluoropropene such as VITON A rubber and KYNAR FLEX 2801 plastomer, are typical of the class of fluorohydrocarbon polymers which are modified to obtain the new materials of this invention.
