METHOD OF MAKING POLYMER ARTICLES AND POLYMER COMPOSITES BY ADDITIVE PROCESSING AND POLYMER AND COMPOSITE ARTICLES

WIPO Patent Application WO/2019/016738

A3

Provided is a method of producing polymer articles comprising (i) subjecting a composition to additive processing in an additive processing device containing at least one energy source wherein the composition comprises particles of a first polymer, particles of a second polymer and at least one binder material capable of binding the polymer particles to form a layer in a part of the composition that has been exposed to the energy source of the additive processing device; (ii) subjecting at least a part of the composition to exposure of the energy source to form a layer comprising the polymer particles and binder material; (iii) repeat step (ii) to form a plurality of layers to create an article; and wherein the first polymer is selected from polymers having a melting point above of at least 250°C or a glass transition temperature (Tg) of greater than 70°C and is not a fluoropolymer and wherein the second polymer is a fluoropolymer. Also provided are materials obtained by this method and articles containing such materials.
