ABSTRACT OF THE DISCLOSURE This invention relates to a process for the manufacture of a neutralized phosphonated ethylene-propylene copolymer having about 1 to about 150 moles of PO3H2 groups which are neutralized with a counterion selected from the group comprising metal cations, ammonium or amines. Elastomeric compositions used for elastomeric articles could include the neutralized phosphonated ethylene-propylene copolymer having about 20 to about 200 parts be weight of a non-polar process oil per 100 parts of the phosphonated copolymer and about 25 to 300 parts by weight of a filler per 100 parts of the phosphonated copolymer, wherein a preferential plasticizer can also be incorporated into the composition. These blend compositions can be readily processed on conventional plastic fabrication equipment into elastomeric articles having excellent physical properties and desirable rubber characteristics.
