HIGH REFRACTIVE INDEX POLYSILOXANES AND THEIR PREPARATION |
| 摘要 |
<p>A high refractive index polysiloxane includes siloxane T units of the formula (I) where A represents an alkylene group having 1 to 4 carbon atoms: n=O or 1; m is at least 1; and Ar is an aryl group substituted by at least one iodine, bromine or chlorine atom, or is a polynuclear aromatic group. The invention includes chlorosilanes having the formula (Ar)m-(A)nSiCl3, useful in forming high refractive index polysiloxanes.</p> |
