Abstract
Soluble, polymerizable oligomers having a number average molecular weight of from about 200 to about 10,000, are obtained by treating triethynylbenzene with an oxygen-carrying, amine-basic cupric salt complex catalyst in the presence of a molar excess over the monomer of an aromatic monacetylenic capping agent. The oligomers are used to form polymers which are adhesives and coatings.
