    摘要： This invention relates to a class of alkenylated toluenediamines having at least one alkenyl group ortho to an amine group. More particularly the toluenediamines are represented by the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are hydrogen, C.sub.1-3 aliphatic, phenyl, halogen or alkoxy radicals, or R.sub.2 and R.sub.4 or R.sub.5 are bridged via an alkylene radical --(CH.sub.2).sub.y -- wherein y=2 to 5, and x is one or two provided that in said formula at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4 or R.sub.5 is C.sub.1 or greater.The above described alkenylated toluenediamines have been found to be well suited as antioxidants and as tri- and tetra functional chain extenders in forming polyurethane/urea elastomers systems and for providing pendant unsaturation for post curing and polymerization.

    摘要： The TPU of this invention contains unsaturation in its polymeric backbone. The unsaturation can be present in the soft segment or in the hard segment or in both the soft and hard segments of the TPU. The TPU can be molded like a thermoplastic, and can be subsequently crosslinked by exposure to electron beam irradiation into thermoset articles having excellent chemical resistance, dimensional stability, set properties, heat resistance, oxidative resistance, and creep resistance. In one embodiment, the TPUs of this invention are the reaction product (1) a hydroxyl terminated intermediate, (2) a polyisocyanate, (3) a saturated glycol chain extender, and (4) a glycol chain extender containing carbon-carbon double bonds, such as the allyl moieties present in trimethylolpropane monoallyl ether. In another embodiment of this invention, the thermoplastic polyurethane which is crosslinkable by e-beam irradiation is comprised of the reaction product of (1) a saturated hydroxyl terminated intermediate, (2) an unsaturated hydroxyl terminated intermediate, wherein the unsaturated hydroxyl terminated intermediate contains carbon-carbon double bonds, (3) a polyisocyanate, and (4) a saturated glycol chain extender.
