摘要： 1. THE PROCESS OF INCREASING THE MOLECULAR WEIGHT OF A POLYMER OF THE CLASS CONSISTING OF TERMINALLY LITHIATED HOMOPOLYMERS OF CONJUGATED DIENES CONTAINING 4 TO 6 CARBON ATOMS AND TERMINALLY LITHIATED COPOLYMERS OF SUCH CONJUGATED DIENES AND A VINYL MONOMER, WHICH COMPRISES JOINING THE UNITS OF THE POLYMER WITH SUBSTANTIALLY EQUIMOLAR AMOUNTS OF TUNGSTEN HEXACHLORIDE AND TRIISOBUTYLALUMINUM WHICH CAUSES JOINING THE POLYMER AND PRODUCTION OF A POLYMER OF INCREASED MOLECULAR WEIGHT.

摘要： 1. A METHOD FOR HALOGENIZING SURFACES OF SYNTHETIC AND/OR NATURAL RUBBER MATERIAL WITH A HALOGEN DONER IN ORDER TO MAKE THESE THESE SURFACES BETTER GLUEABLE TO RUBBER OR OTHER MATERIALS, WHEREIN IN THE PRESENCE OF PYRIDINE A NON-ACIDIFIED SOLUTION OF A N-HALOGEN SULPHONAMIDE HAVING THE GENERAL FORMULA
R-(1,4-PHENYLENE)-SO2-N(-X)-CL(BR)
IN WHICH R IS H OR CH3 AND X IS H OR CL OR BR IS APPLIED TO SUCH SURFACE, AND FURTHER WHEREIN, CALCULATED ON THE APPLIED SOLUTION, THE QUANTITY OF PYRIDINE AMOUNTS TO 0.05 TO 20%, AND THE QUANTITY OF N-HALOGEN SULPHONAMIDE AMOUNTS TO 0.3 TO 20% BY WEIGHT.-

摘要： THE OIL OR SOLVENT RESISTANCE OF SBR SYNTHETIC RUBBERS IS SUBSTANTIALLY IMPROVED BY INCORPORATING IN THE RUBBERS MIX A SUBSTITUTED ACRYLIC ACID OR ACID SALT. THE AMOUNT OF ADDITIVE INCOORPORATED IN THE ELASTOMER ORDINARILY VARIES FROM ABOUT 2.5 TO 5.0 PHR. OF THE ELASTOMER. ZINC METHACRYLATE AND A-METHYL CINNAMIC ACID ARE AMONG THE PREFERRED ADDITIVES.
