Claims
- 1. A silicon-based polymer, comprising an organohydridosiloxane polymer having a structure:(H0-1.0SiO1.5-2.0)n(RSiO1.5)m, wherein a) the sum of n and m is from about 8 to about 5000, and m is selected such that m(n+m) is between about 0.001 and about 0.4; and b) R is selected from the group consisting of alkyls, cycloalkyls, aryls, and mixtures thereof, and wherein the organohydridosiloxane polymer has essentially no hydroxyl or alkoxy groups bonded to silicon atoms.
- 2. A silicon-based polymer as in claim 1 wherein the conformation of said organohydridosiloxane polymer backbone is a cage.
- 3. A silicon-based polymer as in claim 1 wherein said organohydridosiloxane polymer has a weight average molecular weight of between about 400 and about 200,000 atomic mass units (AMU).
- 4. A silicon-based polymer as in claim 1 wherein R is selected from the group consisting of methyl, ethyl, propyl, butyl, pentyl, hexyl, cyclohexyl, phenyl, and mixtures thereof.
- 5. A silicon-based polymer as in claim 1 wherein said organohydridosiloxane resin has a weight average molecular weight of between about 10,000 and about 60,000 atomic mass units.
- 6. A silicon-based polymer as in claim 1 wherein m and y are selected such that m/(n+m) or y/(x+y+z) is between about 0.15 and about 0.25.
