| titleOfInvention | AMORPHOUS HIGH MOLECULAR WEIGHT COPOLYMERS OF ETHYLENE AND .alpha.-OLEFINS |
| abstract | ABSTRACT OF THE DISCLOSURE AMORPHOUS HIGH MOLECULAR WEIGHT COPOLYMERS OF ETHYLENE AND ALPHA-OLEFINS The invention relates to amorphous copolymers of ethylene and one or more alpha-olefins comprising from 3 to 12 carbon atoms, possessing a high molecular weight, a crystallinity index less than or equal to 1.0%, a content of units derived from ethylene comprised between 40 and 60 moles %, a content of units derived from propylene and/or 1-butene between 60 and 40 moles % and a content of units derived from alpha-olefins comprising 5 to 12 carbon atoms of less than or equal to 10 moles %. These copolymers of a practically completely amorphous character advantageously occur in the form of a powder which is easy to handle. They are obtained by copolymerisation in the gas phase by means of a catalyst system of the Ziegler-Natta type, very stereospecific to the polymerisation of propylene. |
