摘要： OIL-EXTENDED SOLID URETHANE ELASTOMERS ARE MADE FROM POLYISOCYYANATES AND POLYHYDROXY DIENE POLYMERS, PREFERABLY HAVING AT LEAST 2.1 PREDOMINANTLY PRIMARY, ALLYLIC TERMINAL HYDROXY GROUPS PER MOLECULE, AND ESSENTIALLY HYDROCARBO EXTENDER AGENTS. THE URETHANE ELASTOMER IS FORMED IN THE PRESENCE OF THE EXTENDER AGENT AND THE POLYHYDROXY POLYMER MAY BE A DIENE HOMOPOLYMER, FOR INSTANCE OF BUTADIENE OR A COPOLYMER OF THE DIENE AND AN ALPHA-MONO-OLEFINIC MONOMER OF 2 TO 12 CABON ATOMS. THE POLYHYDROXY POLYMER IS OF RELATIVELY LOW MOLECULAR WEIGHT AND PREFERABLY HAS GREATER THAN 50% OF ITS UNSATURATION IN THE MAIN HYDROCARBONS CHAIN, FOR INSTANCE ABOUT 50 TO 65% TRANS-1,4-UNSATURATION AND ABOUT 15 TO 25% CIS-1,4-UNSATURATION. THE ELASTOMERS CAN BE MIXED WITH VARIOUS FILLERS INCLUDING CARBON BLACK AND SILICA AND MAY CONTAIN UREA LINKAGES. PREFERRED EXTENDING AGENTS ARE MINERAL OILS HAVING A VISCOSITY OF ABOUT 100 TO 600 SSU AT 100*F.

摘要： THERE IS DISCLOSED A PROCESS FOR POLYMERIZING CONJUGATED DIENE MONOMERS TO FORM RELATIVELY LOW MOLECULAR WEIGHT POLYMERS. THE REACTION CAN BE CONDUCTED AT TEMPERATURES OF ABOUT 100*C. TO ABOUT 200*C. IN THE PRESENCE OF A HYDROGEN PROXIDE CATALYST AND A REACTION MEDIUM WHICH IS AN ESSENTIALLY WATER-INSOLUBLE, TRIHYDROCARBYL ORTHOPHOSPHATE ESTER. THE REACTION SYSTEM HAS AT LEAST TWO LIQUID PHASES FORMED BY THE MONOMER, CATALYST AND REACTION MEDIUM. TRICRESYL PHOSPHATE IS A PREFERRED MEDIUM.
