COATINGS OF FIBRE LIGHT GUIDES FROM AROMATIC POLYAMIDES AND METHOD OF THEIR MANUFACTURE Russian patent published in 2018 - IPC C09D133/24 G02B6/02 C03C25/18 C03C25/32 C08G69/26

Abstract RU 2644891 C1

FIELD: chemistry.

SUBSTANCE: coating of formula I with a molecular weight of 35,000 to 85,000 is proposed: , where x:y = 0-1: 1-0; R₁,

R₃=

R₂, R₄= The method involves pulling the light guide from the workpiece. Stretching it through a spinneret containing a solution of a polyamide of formula I with a viscosity of 2400-18000⋅ mPac in an aprotic dipolar solvent of an amide type, and removing the solvent by heating in an oven.

EFFECT: high thermal stability and satisfactory adhesion to fibre, easy removal with the help of organic solvents of amide type.
