| titleOfInvention | Acetic anhydride modified disproportionated rosin |
| abstract | IN SYNTHETIC RUBBER MANUFACTURING PROCESSES WHEREIN AQUEOUS EMULSIONS OF BUTADIENE AND STYRENE OR BUTADIENE AND ACRYLONITRILE OR OTHER VINYL MONOMERS ARE PREPARED WITH AN EMULSIFYING AGENT CONTAINING A WATER-SOLUBLE SOAP OF A DISPROPORTIONATED ROSIN AND ARE POLYMERIZED IN THE PRESENCE OF A FREE RADICAL CATALYST SYSTEM, THE ADVERSE ACTION OF FREE OXYGEN ON THE POLYMERIZATION IS OFFSET BY HEAT-MODIFYING THE DISPROPORTIONATED ROSIN BEFORE IT IS CONVERTED INTO ITS SOAP. THIS IS DONE BY HEATING IT AT ABOUT 250*-300*C. FOR ABOUT 1 TO 4 HOURS IN ADMIXTURE WITH ABOUT 0.5% TO 5% OF ITS WEIGHT OF ACETIC ANHYDRIDE. |
