According to Table 4 the initial moduli of the block copolymer fibers correspond rather well with the modulus calculated from the mechanical model of Northolt and Van der Hout [19] if shear and chain moduli of PPTA are chosen.Although the tensile strength of the fibers considerably increases with increasing the draw-ratio, its value measured at even the highest draw-ratio, is still somewhat lower than the tensile strength 3-D printed fluoropolymer structures - Arkema Inc.In particular, the invention relates to filament, 3-D printed polyvinylidene fluoride (PVDF) articles, and in particular material extrusion 3-D printing. The articles may be formed from PVDF homopolymers, copolymers, such as KYNAR® resins from Arkema, as well as polymer blends with appropriately defined low shear melt viscosity.

ACS Applied Polymer Materials 2020, 2 (8) , Flexural strength of polymethyl methacrylate copolymers as Maximum flexural strength and modulus resulted from a 40% concentration of IBMA. The flexural strength and modulus values of all copolymer groups were found to be higher than those of the control group. The flexural moduli of the BMA and ethyl-methacrylate groups were similar to those of the control.
