Title:
SYNTHETIC FIBER COATED OPTICAL GLASS FIBER AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPS6120008
Kind Code:
A
Abstract:
The invention provides an optical glass fibre having a synthetic resin coating and a method of manufacturing same, the first layer of the synthetic resin coating being formed from a curable polyether urethane acrylate composition. The glass transition temperature of the synthetic rubber formed after curing is reduced to -50 DEG C. or lower by increasing the molecular weight of the polyether urethane acrylate and, if necessary, by using aromatic instead of aliphatic urethanes. During coating the viscosity is low due to the presence of monofunctional acrylates of low viscosity. The curable synthetic composition exhibits a high curing rate.
