Verfahren zur Reaktivierung eines Sulfonsäureharz-Katalysators

A sulfonated resin catalyst whose activity has lowered as a result of use in the polymerization of silicone oil is reactivated by washing the catalyst with a low molecular weight siloxane medium, volatilizing off the siloxane medium under atmospheric or reduced pressure, and removing water from the...
