Abstract: A process for the preparation of a glass fiber reinforced composition containing a recycled polypropylene includes a) unwinding from a package the continuous glass multifilament strands, b) applying an impregnating agent to the continuous glass multifilament strands to form the impregnated continuous multifilament strands and c) applying the sheath of a first polymer composition around the impregnated continuous multifilament strands to form the sheathed continuous multifilament strands, d) pelletizing the sheathed continuous multifilament strands to form pellets of the sheathed multifilament strands, e) homogenizing the pellets of the sheathed multifilament strands with a second polymer composition, wherein the first polymer composition comprises at least 80 wt % of a recycled polypropylene (PP1), and the second polymer composition includes at least 80 wt % of a second polypropylene (PP2), wherein the MFI of the PP1 and PP2 satisfy the following equation: 0.2≤MFIPP1/MFIPP2≤1.2.
