    Abstract: Joints in an electrical cable are made by joining the ends of the conductors of two cables and applying and then curing a reaction mixture over the joint to form an elastomeric seal. The reaction mixture includes a polyene compound having an average of at least two groups containing aliphatic carbon-carbon double bonds capable of reaction with a thiol group, wherein at least one of such aliphatic carbon-carbon double bonds is separated from each of said aliphatic carbon-carbon double bonds by an aliphatic spacer group having a molecular weight of at least 1000 atomic mass units, an epoxy resin, a curing agent having at least two thiol groups, and a basic catalyst.

    Abstract: Elastomers are prepared from a reaction mixture that contains a polyene compound, an epoxy resin, a thiol curing agent and a basic catalyst. The polyene compound has an average of at least two groups containing aliphatic carbon-carbon double bonds capable of reaction with a thiol group. At least one of said aliphatic carbon-carbon double bonds is separated from each other said aliphatic carbon-carbon double bond by an aliphatic spacer group having a weight of at least 500 atomic mass units. These elastomers are typically phase-separated materials having good elongation and tensile properties.

    Abstract: An epoxy terminated prepolymer formed as a reaction product of a cycloaliphatic epoxide resin and an amine terminated polymeric polyol, and a catalyst that promotes the reaction of the cycloaliphatic epoxide resin and the aminated polyol. The epoxy terminated prepolymer and an anhydride hardener react to form an epoxy elastomer composition having a microphase separated morphology of hard particles, formed with the anhydride hardener reacted with the epoxy terminated prepolymer, dispersed in a soft continuous phase formed from polymeric polyol in the epoxy terminated prepolymer.
