Abstract: A composition useful for additive manufacturing is comprised of a thermoplastic elastomer blended with an aliphatic polyketone, wherein the thermoplastic elastomer is a continuous phase having dispersed therein separated domains of polyketone. The composition is useful for additive printing methods employing heating and extrusion of the composition to form extrudates that are printed an article comprised of fused layers of the composition. The composition facilitates the formation of extrusion based elastomeric additive manufactured articles.

Abstract: Useful thermoplastic polymer powders are formed by a method comprising: cooling a foam comprised of a thermoplastic foam below the brittleness temperature of the thermoplastic polymer, wherein the foam has an average strut dimension of 10 to 500 micrometers, and comminuting the cooled foam to form a thermoplastic polymer powder. The method allows for the efficient grinding of the thermoplastic polymer having improved morphology and desirable characteristics such as dry flow without flow aids.

Abstract: A semicrystalline poly ketone powder useful for additive manufacturing may be made by dissolving a polyketone having differential scanning calorimetry (DSC) monomodal melt peak, at a temperature above 50° C. to below the melt temperature of the polyketone, precipitating the dissolved polyketone by cooling, addition of a nonsolvent or combination thereof. The method may be used to form polyketones having a DSC melt peak with an enthalpy greater than the starting polyketone.

Abstract: An end capped condensation polymer may be formed by heating a condensation polymer in the presence of an end capping compound to form cleaved condensation polymer reacting at least a portion of the cleaved condensation polymer with the end capping compound to form the end capped condensation polymer. The end capped condensation polymers may be used to form additive manufactured articles having high solids loading and improved processing due to improved rheological behavior.
