Anion-exchange resins and process for preparation thereof
Abstract
Abstract WHEREIN R" IS HYDROGEN, ALKYL, ARYL, CYCLOALKYL, ALKYLARYL OR ARYLALKYL CONTAINING 1 TO 10 C ATOMS AND BLENDS OF THE FOREGOING AMINE HOMOPOLYMERS AND COPOLYMERS WITH EACH OTHER AND WITH NON-ION EXCHANGE POLYMERS COMPOSED OF ALPHA-OLEFINS. METHODS FOR THE PREPARATION OF THE FOREGOING ANION-EXCHANGE COMPOSITIONS IN THE FORM OF GRANULES, FILMS AND MEMBRANE ARE DISCLOSED. R"-CH=CH2 WHEREIN X IS A METHYLENE, ARYLENE (HAVING 6 TO 10 C ATOMS) OR CYCLOALKYLENE (HAVING 3 TO 10 C ATOMS) GROUP; R AND R'' ARE THE SAME OR DIFFERENT FROM EACH OTHER AND ARE ALKYL, ARYL, CYCLOALKYL, ALKYLARYL,OR ARYLALKYL GROUPS CONTAINING 3 TO 10 C ATOMS, N IS AN INTEGER FROM 1 TO 10 WHEN X IS A METHYLENE GROUP AND IS 0 OR AN INTEGER FROM 1 TO 10 WHEN X IS AN ARYLENE OR CYCLOALKYLENE GROUP; THE NITROGEN ATOMS OF THE AMINE POLYMER BEING IN THE QUATERNARY STATE. THE COMPOSITIONS OF THE INVENTION INCLUDE HOMOPOLYMERS OF THE FOREGOING AMINES, COPOLYMERS OF THE FOREGOING AMINES WITH OLEFINS HAVING THE FORMULA: R''-N(-R)-X-(CH2)N-CH=CH2 ANION-EXCHANGE COMPOSITIONS COMPOSED OF POLYMERS OF UNSATURATED TERTIARY AMINES HAVING THE FORMULA:
