Claim 1
Independent Claim
87 words
A PROCESS FOR FORMING A CASING OF POLYMER ON PARTICLES OF METAL SO THAT EACH PARTICLE IS SUBSTANTIALLY ENCASED IN A SHELL OF THE POLYMER COMPRISING TREATING METAL PARTICLES WITH THE COMPONENTS OF A MULTI-COMPONENT CATALYST SYSTEM BEFORE SAID COMPONENTS HAVE FULLY REACTED WITH EACH OTHER AND POLYMERIZING AN ALIPHATIC 1-OLEFIN CONTAINING LESS THAN SIX CARBON ATOMS ON SAID PARTICLES BY BRINGING THE CATALYST TREATED PARTICLES INTO CONTACT WITH SAID OLEFIN FOR A SUFFICIENT LENGTH OF TIME AND UNDER CONDITIONS TO FORM A SHELL OF POLYMER THEREON.
