RADIATION CURABLE SATURATED POLYOLEFIN PRESSURE-SENSITIVE ADHESIVE

摘要

Compositions radiation-curable to pressure sensitive adhesives comprise (1) one or more copolymers of alpha -olefins of which 90.1 to 99 mole percent are one or more straight chain alpha -olefins, having 2 to 10 carbon atoms of which at least 55% have 6 to 10 carbon atoms, and 9.9 to 0.1 mole percent are one or more alpha -olefins having 6 to 20 carbon atoms and at least one methylidyne group; (2) an effective amount of a photoactive hydrogen abstracting agent; and, optionally, (3) a tackifying resin. The compositions, on exposure to radiation, provide adhesive films useful in adhesive applications, especially where a bonded article is to be used at elevated temperatures.
