Abstract: A curable adhesive composition for forming a bond between silicone coated optical fibers and fiber connector bodies, said composition comprising: an epoxy resin component; and a curative admixed therewith. The curative comprises an amino-substituted polysiloxane including more than one primary amino group and having a molecular weight from about 150 to about 1,000. The adhesive composition has an initial viscosity, before curing, below about 100 Pascal-seconds, and the bond has a fiber pull-out force above about 1 Kg. Also provided is fiber optic connector including a holder for one or more optical cables, each optical cable having an optical fiber surrounded by strengthening fibers, both of which are surrounded by at least one polymeric coating layer wherein the optical cable is bonded to the connector by means of the curable adhesive.

Abstract: Bulk polymerization process for making radiation curable polyurethanes which comprises:(A) providing the following raw materials:(1) diisocyanate;(2) oligomeric diol>400 molecular weight; and(3) >1 chain extending monomer;(B) reacting the raw materials in a twin screw extruder under the following conditions:(1) molar ratio of isocyanate to hydroxy moieties of about 1;(2) ratio of chain extending monomer to other monomers sufficient to yield a polymer having chain extender incorporated at 0.1 to 10 weight percent;(3) extruder temperature sufficient to initiate and maintain reaction; and(4) residence time sufficient to obtain substantially complete reaction of diisocyanate;(C) cooling product polymer. Polyurethane product has weight average molecular weight greater than 80,000 and acrylate or methacrylate functionality. Process permits continuous production of radiation curable polyurethanes having narrow molecular weight distribution and high tensile strength.
