| titleOfInvention | Process for the polymerization of conjugated dienes |
| abstract | CONJUGATED DIENES ARE POLYMERIZED BY A NEW CATALYST SYSTEM WHICH PERMITS CONTROL OF THE MOLECULAR WEIGHT AND GIVES A MORE EASILY PROCESSED PRODUCT. THIS CATALYST SYSTEM COMPRISES (1) A POTASSIUM HYDROCARBON COMPOUND HAVING 1-10 CARBON ATOMS IN WHICH THE HYDROCARBON PORTION IS A PRIMARY, SECONDARY ORTERTIARY ALKYL OR AN ARYL RADICAL, AND (2) A POTASSIUM ALKOXIDE OF 4-10 CARBON ATOMS, PREFERABLY A TERTIARY-ALKOXIDE. THEDIENE POLYMERS PRODUCED BY THIS PROCESS HAVE CONTROLLABLE MOLECULR WEIGHTS IN THE RANGE OF 25,000 TO 1,000,000 PREFERABLY 100,000 TO 500,000, BROAD MOLECULAR WEIGHT DISTRIBUTION, GLASS TRANSITION TEMPERATURES HIGHER THAN NORMALLY OBTAINED, HIGH DEGREE OF BRANCHING AND ARE MORE EASILY PROCESSED IN THE PRODUCTION OF RUBBER AND OTHER COMPOSITIONS FOR COMMERCIAL USE. |
