Abstract (en)
[origin: EP0987353A1] Polyethylene terephthalate contains 0.1-4 wt.% small rod shaped inclusions of polymethyl methacrylate (PMMA) with Mw = 2 x 10<4>-2 x 10<5>. The fibres and filaments are produced with a draw off speed ≤ 8000 m/minute. Polyethylene terephthalate (PET) fibres and filaments, produced with a draw off speed ≤ 8000 m/minute from PET containing 0.1-4 wt.% polymethyl methacrylate (PMMA) with a weight average molecular weight (Mw) = 2 x 10<4>-2 x 10<5> in the form of small rod shaped inclusions with a lateral particle size 800 nm (measured in extruded, unoriented filaments). An Independent claim is also included for production of PET fibres and filaments by polycondensation of or melting and then melt spinning PMMA modified PET to form unoriented filaments, with the PMMA inclusions.
