  • Process for the production of a shaped article of a heat resistant polymer
    Patent number: 3961009
    Abstract: A process is provided for manufacturing heat resistant polymeric film. A concentrated polymer composition containing solvent is provided, which composition is a solid at room temperature. The composition comprises (a) a polymer having in the repeating units thereof a member selected from the group consisting of precursor units which on heat curing form heterocyclic rings, and a mixture of said precursor units and heterocyclic rings formed from said precursor units and (b) 25-130% by weight of an organic solvent for said polymer, the composition being a solid at room temperature.According to the process, the solid composition is heated to a temperature above room temperature and is extruded into film at this high temperature to form film at a temperature above room temperature and below the curing temperature of the polymer.
