INVESTIGATION OF NEW UNCONVENTIONAL POLYMERIZA TION TECHNIQUES AND DEVELOPMENT OF SEMI-INORGANIC BORON CONTAINING POLYMERS,

Abstract

New unconventional polymerization techniques were employed in this research program where molten zinc chloride, sulfur and Cerrobend alloy were employed as reaction media. The polymeric materials resulting from the B-tri phenylborazole and either N,N' diallylmelamine or dicyandiamide deserve further investigation. The B-trichloro-N-trimethylborozole was synthe sized in about 12% yield. Due to this low yield, the borazole-urea-for-maldehyde resin was not synthesized. A polymeric borazole material resulting from the transamination of B-tri phenylborazole and p-phenylenediamine was syn thesized, having a molecular weight of approxi mately 650. An epoxy novalac cured with B-tri phenylborazole looks encouraging as a liminating resiem for glass reinforced laminates. (Author)
