Process for copolymerizing acenaphthylene with styrene

Claim 1

A PROCESS FOR POLYMERIZING FROM 3-25% BY WEIGHT OF ACENAPHTHYLENE WITH FROM 97-75% BY WEIGHT RESPECTIVELY, OF A MEMBER OF THE GROUP CONSISTING OF STYRENE, ORTHOMETHYL STYRENE, METAMETHYL STYRENE, PARAMETHYL STYRENE AND MIXTURES THEREOF, WHICH CONSISTS OF EMULSIFYING 100 PARTS OF TOTAL MONOMERS IN FROM 100-400 PARTS BY WEIGHT OF WATER WITH THE AID OF FROM 0.1-3.0 PARTS OF AN EMULSIFYING AGENT AND POLYMERZING THE MONOMERS AT A TEMPERATURE RANGING FROM 30*C. BELOW REFLUX TEMPERATURE TO 200*C. AND AT A PRESSURE RANGING FROM 1 ATMOSPHERE TO 500 ATMOSPHERES IN THE PRESENCE OF FROM 0.1-1.0 PART OF A CATALYST MIXTURE CONSISTING OF A COMPOUND TAKEN FROM THE GROUP CONSISTING OF AMMONIUM AND ALKALI METAL SALTS OF PERSULFURIC ACID AND AN ALKANOLAMINE OF THE GROUP CONSISTING OF MONOETHANOLAMINE, DIETHANOLAMINE, TRIETHANOLAMINE, PROPANOLAMINE, AND BUTANOLAMINE, THE WEIGHT RATIO OF THE PERSULFATE SALT TO ALKANOLAMINE VARYING FROM 1:1 TO 1:2, ALL OF SAID ALKANOLAMINE BEING ADDED TO THE AQUEOUS EMULSION BEFORE THE POLYMERIZATION IS INITIATED AND THE PERSULFATE SALT BEING ADDED TO THE REACTION MIXTURE THROUGHOUT POLYMERIZATION.
