Abstract: The invention relates to a tape comprising a plurality of sheathed continuous multifilament strands, wherein each of the sheathed continuous multifilament strands comprises a core that extends in the longitudinal direction and a polymer sheath which intimately surrounds said core, wherein each of the cores comprises an impregnated continuous multifilament strand comprising at least one continuous glass multifilament strand, wherein the at least one continuous glass multifilament strand is impregnated with an impregnating agent in an amount from 0.50 to 15.0 wt %, for example from 0.5 to 10.0 wt % or for example from 10.0 to 15.0 wt % based on the sheathed continuous multifilament strand, wherein the impregnating agent has a melting point of at least 20° C. below the melting point of the thermoplastic polymer composition, has a viscosity of from 2.5 to 200 cSt at 160° C., wherein the continuous glass multifilament strand comprises at most 2 wt % of a sizing composition based on the continuous glass multifilament strand and wherein the polymer sheath consists of a thermoplastic polymer composition, wherein the thermoplastic polymer composition comprises at least 60 wt %, for example at least 80 wt % of a thermoplastic polymer, wherein the amount of impregnated continuous multifilament strand is in the range of 10 to 70 wt % based on the sheathed continuous multifilament strands and wherein the amount of polymer sheath is in the range of 30 to 90 wt % based on the sheathed continuous multifilament strand and wherein the sum of the amount of impregnated continuous multifilament strand and the polymer sheath is 100 wt %.

Abstract: The invention relates to a process for the preparation of a heterophasic propylene copolymer consisting of a propylene-based matrix and a dispersed ethylene-α-olefin copolymer, comprising the steps of a) preparing the propylene-based matrix from propylene and optionally a C2 or C4-C12 α-olefin by contacting at least propylene and optionally C2 or C4-C12 α-olefin with a catalyst in a first gas-phase reactor at a temperature T1 and a pressure P1, b) subsequently preparing the dispersed ethylene-α-olefin copolymer from ethylene and a C3-C12 α-olefin by contacting the ethylene and the C3-C12 α-olefin with a catalyst in a second gas-phase reactor at a temperature T2 and a pressure P2, wherein T1−T2 is in the range from 6 to 25° C., wherein T1>T2, wherein P1 and P2 are in the range from 22 to 30 bar to prepare a heterophasic propylene copolymer (A′).
