Abstract
The present invention provides an ionomer resin having desired properties which is free from the above drawbacks and can readily react in an extruder. That is, the present invention provides a process for producing a modified ionomer resin which comprises mixing ionomer resin wherein 10-60% of the total carboxylic acid moieties are neutralized with sodium ions with basic zinc carbonate under molten conditions to further neutralize 10-40% of the total carboxylic acid moieties with zinc ions.
