261	Process for treating high vinyl liquid polybutadiene with sufluric acid	US3578627D	1969-06-16	US3578627A	1971-05-11	BOUTSICARIS STEPHEN
THE PROCESS DISCLOSED HEREIN COMPRISES THE TREATMENT OF A HIGH-VINYL LIQUID POLYBUTADIENE WITH CONCENTRATED SULFURIC ACID TO CONVERT THE LIQUID POLYBUTADIENE TO A TOUGH THERMOPLASTIC ELASTOMER. THE LIQUID POLYBUTADIENE HAS AT LEAST 60% OF THE REPEATING UNITS THEREIN OF THE PENDENT VINYL TYPE, AND HAS AN AVERAGE% MOLECULAR WEIGHT OF 2,000-10,000. THE POLYBUTADIENE IS TREATED WHILE IN DILUTE SOLUTION IN A HYDROCARBON SOLVENT WHICH IS INERT TO SULFURIC ACID, SUCH AS TOLUENE, BENZENE, XYLENE, ETC. THE SULFURIC ACID IS OF AT LEAST 80% CONCENTRATION, PREFERABLY AT LEAST 95%, AND IS USED IN A PROPORTION OF 5-15 PARTS BY WEIGHT PER 100 PARTS OF POLYMER.
262	Method of improving the tack of ethylene-propylene polymers	US3564079D	1968-01-30	US3564079A	1971-02-16	SOLDATOS ANTHONY C
THIS INVENTION RELATES TO A METHOD OF IMPROVING THE TACK OF ETHYLENE-PROPLENE POLYMERS BY ADDING THERETO A POLYMER OF ISOPRENE AND SUBJECTING THE RESULTANT COMPOSITIONS TO A HEATING CYCLE UNDER CONTROLLED CONDITIONS OF TEMPERATURE AND HUMIDITY.
