Polymerization of crude petroleum hydrocarbon
Abstract
Abstract A TWO-COMPONENT SYSTEM ADAPTED TO REACT TO FORM A HIGHLY CROSS-LINKED THERMOSETTING POLYMER IS DISCLOSED THE FIRST COMPONENT COMPRISES A CRUDE PETROLEUM HYDROCARBON AND AN ARYLENE DIISOCYANATE WHICH IS MISCIBLE WITH THE CRUDE PETROLEUM HYDROCARBON. THE SECOND COMPONENT COMPRISES A CRUDE PETROLEUM HYDROCARBON, HYDROGEN DONOR AND AN ORGANIC ACID. THE HYDROCARBON, HYDROGEN DOEITHER A TERTIARY AMINE HAVING AT LEAST ONE HYDROXYL GROUP OR A MIXTURE OF A TERTIARY AMINE WITH A POLYOL. BOTH THE HYDROGEN DONOR AND THE ORGANIC ACID ARE MISCIBLE WITH THE CRUDE PETROLEUM HYDROCARBON. THERMOSETTING CRUDE PETROLEUM POLYMERS, SUCH AS MAY BE PREPARED FROM THE TWO-COMPONENT SYSTEM ARE ALSO DISCLOSED. SUCH POLYMERS CONTAIN FROM 40 PERCENT TO 80 PERCENT BY WEIGHT CRUDE PETROLEUM HYDROCARBON.
