Process of forming a homogeneous composition of ethylene homopolymer and ethylene-vinyl acetate block copolymer

Claim 1

THE PROCESS OF FORMING A HOMOGENEOUS COMPOSITION CONSISTING ESSENTIALLY OF ETHYLENE HOMOPOLYMER AND AN ETHYLENE-VINYL ACETATE BLOCK COPOLYMER SAID COPOLYMER HAVING THE ESSENTIALLY LINEAR PREFORMED CHAIN OF POLYETHYLENE MAINTAINED SUBSTANTIALLY INTACT WITH THE VINYL ACETATE POLYMER GROUPS ATTACHED AT A TERMINUS OF SAID CHAIN WHICH COMPRISES ADDING SIMULTANEOUSLY OXYGEN AS THE SOLE EFFECTIVE CATALYST AND VINYL ACETATE MONOMER TO A REACTION ZONE CONTAINING POLYETHYLENE FORMED BY SUBJECTING ETHYLENE TO THE ACTION OF A CATALYST CONSISTING ESSENTIALLY OF A ASLT OF A MEMBER OF THE GROUP CONSISTING OF TI, ZR, HF, V, NB, TA, CR, MO AND W AND AN ALUMINUM TRIALKYL, SAID POLYETHYLENE STILL CONTAINING THE METALIC CATALYST RESIDUE BONDED TO ITS TERMINAL CARBON ATOM IN A CARBONMETAL BOND, THEREBY FORMING A REACTION PRODUCT CONSISTING OF VINYLE ACETATE HOMOPOLYMER AND THE AFORSAID HOMOPOLYMER AND COPOLYMER AND THEREAFTER SEPARATING SAID VINYL ACETATE HOMOPOLYMER FROM THE REACTION PRODUCT; SAID COPOLYMER BEING TERMINED ON ONE END BY ETHYENE AND ON THE OTHER END BY VINYL ACETATE, SAID POLYETHYLENE CATALYST BEING PRESENT IN AN AMOUNT EQUAL TO 0.001 TO 1.0 PART OF SAID POLYETHYLENE CATALYST/PART POLYETHYLENE.
