Cross-linked optical siloxane polymer |
| abstract |
Abstract The invention provides a cross-linked optical siloxane polymer having a group for modifying the refractive index of the polymer which is introduced in a side chain of the polymer by a hydrosilyl reaction. The hydrosilyl reaction may proceed according to one of the following two schemes. In the first scheme, a compound (A) having a carbon-carbon unsaturated bond and a group for modifying a refractive index, and a siloxane polymer (B) having a silicon hydride group are reacted wherein the molar ratio of the silicon hydride group to the carbon-carbon unsaturated bond is more than 1. In the second scheme, a compound (A') having a silicon hydride group and a group for modifying a refractive index, and a siloxane polymer (B') having a carbon-carbon unsaturated bond are reacted wherein the molar ratio of the carbon-carbon unsaturated bond to the silicon hydride group is more than 1. The resulting polymer is cross-linked by a hydrosilyl reaction of the unreacted silicon hydride groups of the siloxane polymer (B) with a compound (C) having at least two carbon-carbon unsaturated bond when the system (1) is employed, or by a hydrosilyl reaction of the unreacted carbon-carbon unsatur-ated bonds of the siloxane polymer (B') with a compound (C') having at least two silicon hydride groups when the system (2) is employed. The refractive index of the resulting siloxane polymer is easily and precisely modified and can be used for the manufacture of a variety of optical elements. |
