ABSTRACT:
New modified non-melt-fabricable polytetrafluoroethylene resins have now been found which can be compounded with elastomers or plastics without the deleterious agglomeration or fibrillation that occurs with known modified non-melt-fabricable polytetrafluoroethylene resins. The resins are made of recurring units of tetrafluoroethylene, and recurring units of at least one comonomer selected from hexafluoropropylene or perfluoro (alkyl vinyl ether) wherein the alkyl group is of 1-4 carbon atoms, said comonomer present in amounts sufficient to produce the effect recited in the first sentence.
