Carbon-polyolefin compositions and process for making same

Claim 1

A PROCESS FOR ENCASING CARBON PARTICLES IN A SHELL OF POLYMER TO FORM A FREE-FLOWING GRANULAR MATERIAL OF DISCRETE PARTICLES, EACH OF SAID DISCRETE PARTICLES HAVING A CARBON CENTER SUBSTANTIALLY ENCASED IN A SHELL OF POLYMER, SAID SHELL BEING SUBSTANTIALLY PROPORTIONAL IN SIZE TO THE CARBON CENTER CONTAINED THEREIN, WHICH COMPRISES TREATING CARBON PARTICLES WHICH HAVE BEEN THROUGHLY DRIED TO A SUBSTANTIALLY ANHYDROUS STATE WITH NOT SUBSTANTIALLY LESS THAN 0.06 AND NOT SUBSTANTIALLY MORE THAN 2.4 MILLIMOLES PER CARBON PARTICLE GRAM OF ONE COMPONENT OF A MULTI-COMPONENT CATALYST SYSTEM THE COMPONENTS OF WHICH, UPON REACTION WITH EACH OTHER, FROM ACTIVE SITES OF POLYMERIZATION INITIATOR EFFECTIVE FOR POLYMERIZING 1-OLEFINS TO AFFIX SAID ONE COMPONENT TO SAID PARTICLES, REACTING THE TREATED CARBON PARTICLES WITH THE REMAINING COMPONENT OF THE CATALYST SYSTEM TO REACT SAID ONE COMPONENT ON SAID PARTICLES WITH SAID REMAINING COMPONENT TO SAID CATALYST SYSTEM AND TO FORM AND AFFIX ON SAID PARTICLES THE ACTIVE SITES OF POLYMERIZATION INITIATOR AS SAID SITES ARE FORMED BY THE REACTION OF SAID COMPONENTS AND, THEREAFTER, POLYMERIZING AN ALIPHATIC 1-OLEFIN CONTAINING LESS THAN 6 CARBON ATOMS ON SAID PARTICLES BY BRINGING THE CATALYST TREATED PARTICLES WITH SAID ACTIVE SITES OF POLYMERIZATION INITIATOR FORMED THEREON INTO CONTACT WITH SAID 1-OLEFIN TO POLYMERIZED SAID OLEFIN ON SAID CARBON PARTICLES TO FORM A SHELL OF POLYMER ON EACH OF SAID PARTICLES OF CARBON, SAID SHELLS BEING SUBSTANTIALLY PROPORTIONAL IN SIZE TO THE CARBON PARTICLE CONTAINED THEREIN.
