Ethylene/sulfur dioxide bipolymers and method of making
Abstract
Abstract BIPOLYMERS OF ETHYLENE AND SULFUR DIOXIDE WHICH ARE ESSENTIALLY FREE OF 1:1 MOLAR RATIO OF ETHYLENE AND SULFUR DIOXIDE ARE PROVIDED. PROCESSES FOR PREPARING THESE BIPOLYMERS ARE ALSO PROVIDED. THE BIPOLYMERS CONSIST ESSENTIALLY OF AT LEAST ABOUT 50 PERCENT BY WEIGHT ETHYLENE AND ABOUT 0.1 TO 50 PERCENT BY WEIGHT SULFUR DIOXIDE. THE ABSENCE OF 1:1 MOLAR RATION OF ETHYLENE AND SULFUR DIOXIDE ARE EVIDENCED BY THE BIPOLYMERS HAVING AN ABSORPTION BAND AT ABOUT 16 TO 17U IN THE INFRARED SPECTRA AND BEING ESSENTIALLY FREE OF TWO ABSORPTION BANDS BETWEEN 13.5 AND 14U IN THE INFRARED SPECTRA, RESPECTIVELY. BY VARYING THE AMOUNT OF THE HIGHLY POLAR SULFUR DIOXIDE IN THE BIPOLYMERS, SHAPED ARTICLES (E.G., MOLDED ARTICLES AND FILMS) FROM THE BIPOLYMERS OR FROM BLENDS OF THE BIPOLYMERS WITH OTHER SOLID ORGANIC POLYMERS, SUCH AS A VINYL CHLORIDE POLYMER, CAN BE FLEXIBLE OR RIGID, AND POSSESS IMPROVED PROPERTIES OF POLYETHYLENE.
