The inventive composition comprises at least one polyorganosiloxane A (POS) which can be cationically and radically cross-linked by functional cross-linking groups (GFR) and a primer C chosen from onium borates, characterized in that the inventive composition also comprises molecules (POS D) which are substituted by secondary functional groups (GFS) carried by silicon atoms and selected from those that include at least one alkoxy and/or epoxy and/or carboxy motif and optionally a charge (e.g. silica). The invention can be used with anti-friction varnishes for RTV silicone coatings for material used in air bags, thermal transfer ribbons or packing films.Type: GrantFiled: April 5, 2000Date of Patent: June 7, 2005Assignee: Rhodia ChimieInventors: Jean-Louis Bertry, Jean-Marc Frances, Fabrice Bohin, Christian Priou

Patent number: 6864329Abstract: Provided herein is an inorganic-organic hybrid conjugated polymer having opto-electronic function and a process to make the same. The disclosed polymer contains inorganic or organic bulky groups in the polymer backbone or as pedant groups and has a general formula: wherein: A is a bulk group, comprising at least one silsesquioxane, serving as a positional anchor for the polymer. S serving as a spacer includes alkyl, cycyloalkyl group of from 1 to 30 carbon atoms, or aryl or substituted aryl of from 6 to 50 carbon atoms, or herteroaryl or substituted heteroaryl of from 4 to 50 carbons. CP represents any conjugated polymer segment at least one portion thereof comprising an opto-electronic function, for example, polyacetylenes, polyphenylenes, polyphenylenevinylenes, polythiophenes, polypyrroles, polyanilines, polyfluorences, and any conjugated co-polymer segment. x, y and z are positive integers, where x and z is equal or greater than 1.Type: GrantFiled: September 3, 2002Date of Patent: March 8, 2005Assignee: American Dye Source, Inc.Inventors: Steven Xiao, My T.

Patent number: 6846895Abstract: A novel polysiloxane having the following structural units (I) and/or (II) and the structural unit (III), wherein A1 and A2 are an acid-dissociable monovalent organic group, R1 is hydrogen, monovalent (halogenated) hydrocarbon, halogen, or amino, R2 is monovalent (halogenated) hydrocarbon group, or halogen. A method of preparing such a polysiloxane, a silicon-containing alicyclic compound providing this polysiloxane, and a radiation-sensitive resin composition comprising this polysiloxane are also provided. The polysiloxane is useful as a resin component for a resist material, effectively senses radiation with a short wavelength, exhibits high transparency to radiation and superior dry etching properties, and excels in basic resist properties required for resist materials such as high sensitivity, resolution, developability, etc.Type: GrantFiled: February 12, 2003Date of Patent: January 25, 2005Assignee: JSR CorporationInventors: Haruo Iwasawa, Tsutomu Shimokawa, Akihiro Hayashi, Satoru Nishiyama
