The current invention concerns a textile coating composition comprising an aqueous emulsion of a midblock sulfonated styrenic block copolymer and a poly(vinyl alcohol). It also concerns a method for preparing the textile coating composition and its application. It also concerns fabrics on which the coating compositions have been applied.

A 3D-printable blend comprising a thermoplastic elastomer and a polymer. The thermoplastic elastomer is selected from poly(styrene-b-isobutylene-b-styrene) (SIBS), poly(St-b-butadiene-b-St) (SBS), poly(St-b-isoprene-b-St) (SIS), and their hydrogenated derivatives. The polymer is selected from polystyrene (PSt), poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and blends of PSt and PPO. The blends may be made into filaments suitable for use in the production of 3D printed articles.
