Abstract
A process for producing a low cross-linking-density gel capable of effectively inhibiting light scattering in joining the ends of optical fiber cores with each other. The process is characterized by involving the compounding step for adjusting a flexible silicone gel material to have a specified refractive index and the reaction step for cross-linking the flexible silicone gel material obtained in the above step in a binding region with a low cross-linking density, thus yielding a low cross-linking-density gel.
Claims16
A method for producing a low cross-linking-density gel, comprising:
- a compounding step for adjusting a flexible silicone gel material to have a specified refractive index, and
- a reaction step for causing the flexible silicone gel material adjusted in the compounding step to cross-link in a binding region where cross-linking density is low, thereby producing a low cross-linking-density gel.
A method for producing a low cross-linking-density gel, comprising:
- a compounding step for adjusting a flexible silicone gel material to have a specified refractive index,
- a synthesizing step for synthesizing a composition by adding a cross-linking agent to the flexible silicone gel material adjusted in the compounding step,
- a filling step for filling the composition into a syringe,
- a sealing step for sealing the syringe, and
- a reaction step for heating the sealed syringe to cause the composition to undergo an addition reaction in a binding region where cross-linking density is low, thereby producing a low cross-linking-density gel in the syringe.
A low cross-linking-density gel, characterized in that it is produced by causing a flexible silicone gel material adjusted to have a specified refractive index to undergo an addition reaction so as to cross-link in a binding region where cross-linking density is low.
