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: Polymer powders useful for additive manufacturing may be made by contacting carbon dioxide and a crystallizable polymer having at least one carbonyl, sulfur oxide or sulfone group; permeating the carbon dioxide into the polymer for a crystallizing time sufficient to induce crystallization forming an induced crystalized polymer; removing the carbon dioxide; and forming induced crystalized polymer particles having a D90 particle size of at most 300 micrometers and average particle size of 1 micrometer to 100 micrometers equivalent spherical diameter. The carbon dioxide is desirably supercritical carbon dioxide for at least a portion of the crystallizing time. The polymer powders upon heating during additive manufacturing may result in a polymer having less crystallinity or become amorphous.

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: In one instance a semicrystalline polyketone powder useful for additive manufacturing is comprised of a bimodal melt peak determined by an initial differential scanning calorimetry (DSC) scan at 20° C./min and a D90 particle size of at most 300 micrometers and average particle size of 1 micrometer to 150 micrometers equivalent spherical diameter. In another instance, A composition is comprised of a semicrystalline polyketone powder having a melt peak and a recrystallization peak, wherein the melt peak and recrystallization peak fail to overlap.

Abstract: A semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. The semi-crystalline blended polymer displays a DSC melt peak enthalpy of at least about 3 joules/g. The semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. The semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.

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: A polymeric composition comprised of poly(methylmethacrylate) (PMMA) and polylactic acid (PLA) having a surface charge potential of at least about 50 volts in the absence of any other charge enhancing component may be made by melt blending PMMA and PLA, extruding the melt blend through a die and cooling at a rate through Tg of the PLA of at 10° C./min to 1000° C./second. The polymeric composition may be made by melt blowing into a nonwoven fabric. The nonwoven fabric may be charged to a surface potential of at least about 50 electron volts. Such filters may have greater than 95% efficiency at a pressure drop of less than 2 mm Hg even after being exposed to high temperatures (~70° C.) for an hour or more.

Abstract: Copolymers of condensation polymers are formed by a method of cleaving and reacting with a chain extender to form an end capped cleaved condensation polymer that is further reacted with a second compound that may be comprised of a further chain extender and condensation polymer that react with a reactive group still remaining in the chain extender capping the cleaved condensation polymer. The method allows the formation of block copolymers, branched copolymers and star polymers of differing condensation polymers bonded through the residue of a chain extender.
