Modified polytetrafluoroethylene resins and blends thereof.

摘要

Dispersion-process-produced, non-melt-processible, particulate, core-shell, tetrafluoroethylene copolymer comprising recurring units of tetrafluoroethylene and modifying recurring units of at least one ethylenically unsaturated comonomer that is copolymerizable with the tetrafluoroethylene, the number of recurring units of comonomer in the shell being sufficient to enable the copolymer to compound uniformly with an elastomer or plastic without forming visible agglomerates, and blends thereof with elastomeric and plastic resins.
