Abstract: A glass fiber-reinforced thermoplastic polymer composition has a sheathed continuous multifilament strand including a core that extends in the longitudinal direction and a polymer sheath which intimately surrounds the core, wherein the core has an impregnated continuous multifilament strand having at least one continuous glass multifilament strand, wherein the at least one continuous glass multifilament strand is impregnated with an impregnating agent, the polymer sheath is a thermoplastic polymer composition including a thermoplastic polymer, wherein the thermoplastic polymer contains a polyester having a weight average molecular weight of 15,000 to 80,000 Daltons as measured by gel permeation chromatography (GPC) using polystyrene standard and as measured by differential scanning calorimetry with a heating rate of 20° C./minute on first heating according to ASTM D3418-08, at least one crystalline melting point (Tm) of 200 to 290° C.
