Patent ID: 7834094

Claim:
An alpha-olefin homo- or copolymer composition comprising at least one (i) alpha-olefin homo- or copolymer component, wherein (a) the alpha-olefin homo- or copolymer composition is a reactor-made polymer composition not subjected to a post reactor treatment that further modifies the MFR of the polymer product or a treatment that modifies the oligomer content or MFR of the composition, the composition comprising C 6 - C 15 -oligomers in an amount which satisfies the following equation (1): “oligomer content”≦ e [3.5+(0.504·1n(MFR 2 ))] (1) wherein “oligomer content” is the amount, in ppm, of alpha-olefin C 6 -C 15 -oligomer and “MFR 2 ” is the MFR 2 value of the alpha-olefin homo- or copolymer composition as determined from the composition, and (b) MFR 2 of said composition is at least 0.001 g/10 min, the composition is produced in a single stage polymerization process in the presence of solid catalyst particles comprising a compound of a transition metal of Group 3 to 10 of the Periodic Table, or of an actinide or a lanthanide, the solid catalyst particles having an average size range of 5 to 200 μm and a surface area of less than 20 m 2 /g, the solid catalyst particles being prepared by an emulsion and solidification method comprising (a) forming a liquid/liquid emulsion system, which contains a homogeneous solution of at least one catalyst component, said solution being dispersed as droplets in a solvent immiscible therewith and forming the dispersed phase of the liquid/liquid emulsion system, b) solidifying said dispersed droplets to form solid catalyst particles having a predetermined size range, and c) removing the solvent from the reaction mixture in order to obtain said solid catalyst particles, and recovering the particles.
