Abstract
This invention relates to extrusion and injection moldable type elastomeric compositions having a viscosity at 200.degree. C. at 0.73 sec.sup.-1 of about 8.times.10.sup.4 to about 8.times.10.sup.6 poises. The compositions used for elastomeric articles include neutralized sulfonated co- and terpolymers of octene-1/ethylene/ENB or sulfonated terpolymers of hexene-1/ethylene/ENB, about 15 to about 200 parts by weight of a non-polar process oil per 100 parts of polymer; about 50 to about 300 parts by weight of a filler per 100 parts of polymer; and a preferential plasticizer at about 1 to about 50 parts by weight per 100 parts of the sulfonated elastomeric polymer. The composition may also include a crystalline polyolefinic thermoplastic at less then about 100 parts per hundred by weight. These blend compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment into elastomeric articles having excellent physical properties and desirable rubbery characteristics.
