Abstract

A substantial effort in this laboratory has been directed toward the synthesis and characterization of acetylene terminated oligomers for use as addition-curable, moisture-resistant, thermoset systems. Early work on the acetylene-terminated phenylquinoxalines12 demonstrated the moisture insensitivity of the product generated from the thermal cure. Studies of various difunctional acetylene-terminated monomers has demonstrated3 that the polymerization is a free radical propogation of the acetylene moiety to a linear conjugated polyene. The kinetic chain length of this reaction is unusually short (6–8 acetylene units) and termination is first order.
