PROCESS AND APPARATUS FOR THE PRODUCTION OF AN ELASTOMERIC OPTICAL FIBRE, AND OPTICAL FIBRE

摘要

The process for the production of an elastomeric optical conductor fibre (16) composed of plastic draws a fibre (16) composed of a high-viscosity liquid reactive starting material (A), and the starting material (A) is added by way of a nozzle (18) to a reaction apparatus (5), to which a liquid inert towards the starting material (A) has been charged, and at least partial crosslinking of the starting material (A) takes place in the reaction apparatus (5). The elastomeric plastic of the optical conductor fibre (16) is in particular a three-dimensionally crosslinked polyurethane.
