More Information
Summary:A copolymer of 1-butene and at least a C8-C12 alpha-olefin derived units, preferably at least 1-octene derived units, containing from 0% to 2% by mole of propylene or pentene, having a content of C8-C12 alpha-olefin derived units higher than 0.2% and lower than 7.2% by mole; endowed with the following features: a) the melting point measured by DSC (TmII) and the C8-C12 alpha-olefin molar content fulfil the following relationship: 0<TmIK−6.5×C+104 wherein C is the molar content of C8-C12 alpha-olefin derived units and TmII is the highest melting peak in the second melting transition; b) intrinsic viscosity (IV) measured in tetrahydronaphthalene at 135° C. comprised between 0.8 and 5 dL/g; and c) isotactic pentads mmmm higher than or equal to 90%; pentads (mmrr+mrrm) lower than 4 and pentads rmmr not detectable at 13C NMR.
