Process for producing high softening point hydrocarbon resin having good solubility |
| abstract |
A PROCESS FOR PRODUCING LIGHT COLORED AROMATIC HYDROCARBON RESINS HAVING A HIGH SOFFTENING POINTS OF ABOVE 140* C., GOOD SOLUBILITY IN HYDROCARBON SOLVENTS AND LOW BROMINE VALUE, WHICH COMPRISES USING A THERMAL CRACKED PETROLEUM FRACTION HAVING A BOILING RANGE OF 140-220*C., BELOW 7 WT. PERCENT OF STYRENE CONTENT, AND ABOVE 5 WT. PERCENT OF TOTAL CONTENT OF INDDENE AND ITS ALKYL DERIVATIVES, POLYMERIZING SAID FRACTION IN THE PRESENCE OF A BORON TRIFLUORIDE TYPE CATALYST AT A TEMPERATURE BETWEEN -30 TO +40*C. WITHIN A PERIOD OF 10 MINUTES TO 15 HOURS UNDER ADDITON OF PHENOL AND/OR AKYLPHENOL, REMOVING SAID CATALYST AFTER POLYMERIZATION, AND RECOVERING SAID RESIN AFTER SEPARATION OF UNPOLYMERIZED FRACTION AND LOW MOLECULAR WEIGHT POLYMERS FROM THE RESIN-CONTAINING SOLUTION BY EVAPORATION OR DISTILLATION. |
