Liquid, radiation-curable resin for the coating of optical waveguides |
| 摘要 |
The production of coatings for optical waveguides requires liquid, radiation-curable resins which have a high curing rate and give coatings having the requisite properties, where the primary coating must have a freezing range </= -40@C and there must be no compatibility problems between the primary coating and the secondary coating. This is achieved by a resin which is (a) a product of the reaction of a polyalkylene glycol diglycidyl ether with glycerol di(meth)acrylate or pentaerythritol tri(meth)acrylate or (b) a product of the reaction of (meth)acrylic acid or (meth)acrylyl chloride or isocyanatoalkyl (meth)acrylate with a product of the reaction of the polyalkylene glycol diglycidyl ether and (b1) water, a low-molecular-weight diol or a low-molecular-weight polyol or (b2) (meth)acrylic acid.
