    摘要： Flame retardant, thermoplastic molding compositions of high electroconductivity comprising between about 2% and about 45% by weight of finely divided conductive carbon black particles substantially uniformly dispersed within a cementitious matrix having a chlorine content of at least about 24% by weight and composed predominantly of substantially thermoplastic resins not substantially less than half of which by weight are vinyl chloride polymers which have a vinyl chloride content of at least about 70% by weight and K-values between about 45 and about 70, and wherein said cementitious matrix also contains from about 1% to about 15% by weight of a well balanced lubricant/stabilizer combination comprising lubricants which are solid at temperatures up to at least about 50.degree. C., together with effective stabilizers, are disclosed.

    摘要： Methods of fabricating a polymeric implantable device, such as a stent, with improved fracture toughness through annealing a polymer construct below the glass transition temperature of the polymer of the construct prior to a deformation step are disclosed herein. The deformation of the construct induces crystallization in the polymer construct through strain-induced crystallization. The annealing of the polymer construct accelerates the crystallization induced during the deformation and results in an increase in crystallite density with smaller crystallites as compared to deformation of a tube that has not been annealed. A stent scaffolding is then made from the deformed tube.
