ELASTOMERIC COPOLYMERS OF ETHYLENE WITH PROPYLENE AND PROCESS FOR THEIR PREPARATION |
摘要 |
Amorphous copolymers of ethylene with propylene, and optionally with minor amounts of polyenes, have the following characteristics: (A) the % content by mole of propylene in the copolymer (%P) and the triads ratio EPE/(EPE+PPE+PPP) satisfy the following relationship: 0.01%P + EPE/(EPE+PPE+PPP) ? 1 (B) less than 2% of the CH2 groups in the chain are in sequences (CH2)n, wherein n is an even number. These copolymers are obtainable by operating in the presence of particular metallocene catalysts having two fluorenyl groups joined together through a bridging group.
