Abstract: Pigmented aqueous coating composition providing good blocking and elasticity properties comprises a blend of a seeded multistage polymer latex(es) having at least one soft and at least one hard polymer phases and a non-film-forming polymer latex(es), the seed polymer(s) having a Tg?10° C. lower than that of the hard polymer phase(s) and preferably having a Tg?10° C. higher than that of the soft polymer phase(s), and the multistage polymer(s) preferably having amino functionality incorporated by an imination reaction.

Abstract: A process for forming a continuous filament yarn from a melt-spinnable synthetic linear polymer and novel yarns of polyethylene terephthalate and yarns of polyhexamethylene adipamide produced by the process, the process comprising extruding the molten polymer through a shaped orifice to form a molten filamentary material, passing the molten filamentary material through a solidification zone, passing the solidified filamentary material through a conditioning zone provided with a gaseous atmosphere at a temperature above the glass transition temperature of the material and below its melting temperature, withdrawing the resulting filamentary yarn from the conditioning zone and winding up such yarn, characterized in that the gaseous atmosphere in the conditioning zone is compressed steam at an absolute pressure in excess of 5 psig and preferably, in the case of a yarn of polyethylene terephthalate, between 50 and 156 psig and preferably, in the case of a yarn of polyhexamethylene adipamide, between 14 and 70 psig

Abstract: An electrically conductive fibre formed from a thermoplastic organic polymer and having a zero or positive temperature coefficient of resistance. It is produced by the sequential steps of embedding and/or dispersing electrically conductive carbon particles into an outer region of the fibre, removing at least some of any free, unadhered carbon particles, if any are present, from the surface of the fibre by washing, and heating the fibre to a temperature whereby its temperature coefficient of resistance becomes zero or is converted to a positive value.
