Claims
- 1. An organohydridosiloxane resin with high organic content comprising a polymer having a general formula:
- (H.sub.0-1.0 SiO.sub.1.5-2.0).sub.n (RSiO.sub.1.5).sub.m ;
- wherein the sum of n and m is from about 8 to about 5000 and m is selected such that m/(n+m) is 0.4 or greater;
- wherein R is selected from chloro-substituted and unsubstituted normal and branched alkyl groups, chloro-substituted and unsubstituted cycloalkyl groups, aryl groups, and mixtures thereof; and
- wherein the polymer has essentially no hydroxyl or alkoxy groups bonded to silicon atoms.
- 2. The polymer as in claim 1 wherein the conformation of said organohydridosiloxane resin is a cage.
- 3. The polymer as in claim 1 wherein said organohydridosiloxane resin has a weight average molecular weight of between about 400 and about 200,000 atomic mass units.
- 4. The polymer as in claim 1 wherein said organohydridosiloxane resin has a weight average molecular weight of between about 20,000 and about 40,000 atomic mass units.
- 5. The polymer as in claim 1 wherein `R` is an organic substituent selected from the group consisting of chloro-substituted and unsubstituted, normal and branched alkyl groups having between 1 and 20 carbons, chloro-substituted and unsubstituted cycloalkyl groups having between 4 and 10 carbons, aryl groups having between 6 and 20 carbons, and mixtures thereof.
- 6. The polymer as in claim 1 wherein `R` is an organic substituent selected from the group consisting of methyl, t-butyl, phenyl, benzyl, chloromethyl and mixtures thereof.
