Bulk neutralisation of sulfonated elastomeric polymers.

摘要

A process for neutralizing a sulphonated elastomeric polymer having 5 to 60 meq neutralized sulphonate groups per 100 gm of sulfonated polymer wherein the polymer is mixed with an additive, the mixture thereby formed is compounded at a temperature of less than 66 DEG C into the homogeneous state, a neutralizing agent is added to the mixture which is further compounded so as to neutralize at least partially the sulphonated polymer.
