Polymerization of olefin with polar monomers in the presence of ziegler type catalyst systems

Claim 1

A SUBSTANTIALLY LINEAR COPOLYMER OF AT LEAST ONE MONOETHYLENEICALLY UNSATURATED ALPHA OLEFIN HAVING FROM 2 TO 8 CARBON ATOMS AND A MONOETHYLENICALLY UNSATURATED POLAR MONOMER SELECTED FROM THE GROUP CONSISTING OF VINYL ALKANOATESHAVINNG UP TO ABOUT 18 CARBON ATOMS, AND ALKYL ACRYLATES WHEREIN SAID ALKYL GROUP HAS UP TO ABOUT 6 CARBON ATOMS, SAID COPOLYMER BEIG THE PRODUCT RESULTING FROM A PROCESS COMPRISING: (A) GRADUALLY ADDING SAID POLAR MONOMER TO A REACTION ZONE COMPRISING SAID ALPHA OLEFIN AND A CATALYST SYSTEM CONSISTING ESSENTIALLY OF (1) FROM ABOUT 10 TO ABOUT 160 MOLES, PER 1000 LITERS OF REACTION ZONE, OF AT LEAST ONE COMPOUND OF AN ELEMENT OF GROUP IIIB OF THE PERIODIC TABLE (MENDELEEFF), SAID COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF THE ALKYLS, ARYLS AND ALKYL HALIDES; (2) FROM ABOUT 0.1 TO ABOUT 5 MOLES, PER MOLE OF SAID COMPONENT (1), OF A COMPOUND OF AT LEAST ONE ELEMENT OF GROUPS IVA, VA, VIA, VIIA AND VIII OF THE PERIODIC TABLE (MENDELEEFF), SAID COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF THE HALIDES, OXYHYDROCARBONS OXYHALIDES, AND OXIDES, SAID ELEMENT HAVING A VALENCE ABOVE ITS MOST REDUCED STATE; AND (3) FROM ABOUT 0.1 TO ABOUT 3 NOLES, PER MOLE OF SAID COMPONENT (1) OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF LITHIUM, SODIUM, POTASSIUM, BERYLLIUM AND MAGNESIUM ALKYLS HAVING UP TO ABOUT 6 CARBON ATOMS; SAID ADDITION OF POLAR MONOMER TO SAID REACTION ZONE BEING AT A RATE OF BETWEEN ABOUT 0.01 AND 1.0 MILLIMOLE PER MILLIMOLE OF SAID CATALYST COMPONENT (2) PER MINUTE; AND (B) COPOLYMERIZING SAID MONOMERS AT A TEMPERATURE BETWEEN ABOUT 20* AND 120*C. AND A PRESSURE BETWEEN ABOUT 100 AND 500 P.S.I.G.
