<p>1298453 Cross-linking polymers NATIONAL RESEARCH DEVELOPMENT CORP 31 Dec 1969 [2 Jan 1969] 393/69 Heading C3P [Also in Division C7] A polymer is evaporated and deposited on a cooled substrate, and during deposition it is irradiated with, e.g. ultra-violet light to cause cross-linking of the polymer. The polymer may be polyethylene, polypropylene, P.T.F.E., polytetrafluoropropylene, nylon or polycarbonates. The irradiation may be continued after deposition.</p> |
