ABSTRACT:
A method of increasing the strength and high temperature resistance of aromatic thermoplastic polymers by adding thereto an appropriate amount of certain biphenylene terminated compounds, then heating the mixture to a crosslinking reaction temperature. The biphenylene additive has been found to function as a plasticizer for the polymer, making it easier to work, mold, extrude, etc. prior to the heating step.
