Abstract: A CATALYST COMPONENT FOR OLEFIN (CO)POLYMERIZATION, AND IN PARTICULAR FOR THE PREPARATION OF LLDPE, COMPRISING Mg, Ti, HALOGEN AND AN ELECTRON DONOR COMPOUND (ED) BELONGING TO ETHERS, ESTER, AMINES,KETONES, OR NITRILES, CHARACTERIZED IN THAT THE MOLAR RATIO Mg/Ti IS HIGHER THAN 5, AND THE MOLAR RATIO ED/Ti IS HIGHER THAN 3.5. THE SAID CATALYST COMPONENTS DISPLAY A HOMOGENEOUS DISTRIBUTION OF THE COMONOMER IN AND AMONG THE COPOLYMER CHAINS.

Abstract: PROCESS FOR THE POLYMERIZATION OF OLEFINS CH2=CHR, IN WHICH R IS HYDROGEN OR A HYDROCARBON RADICAL WITH 1-12 CARBON ATOMS, CARRIED OUT IN THE PRESENCE OF A CATALYST COMPONENT (A) COMPRISING MG, TI AND HALOGEN AS ESSENTIAL ELEMENTS AND OF A CATALYST COMPONENT (B) CAPABLE TO PRODUCE, UNDER THE SAME POLYMERIZATION CONDITIONS, A POLYMER WITH AN AVERAGE PARTICLE SIZE LOWER THAN THAT OBTAINABLE WITH THE SAID CATALYST COMPONENT A. THE SAID PROCESS PROVIDES POLYMERS WITH INCREASED BULK DENSITY.
