Abstract
The rheological properties of suspensions based on paraffin and LDPE, in which polyphenylene sulfone powder is dispersed, intended for powder injection molding and 3D printing were studied. Compositions with a polymer content of up to 50 vol % are pseudoplastic liquids that lose their flow ability upon reaching 60 vol %. Suspensions with 30 and 40 vol % polyphenylene sulfone have optimal technological properties during injection molding, combining the required rheological properties and strength of products. At the same time, compositions with PE have sufficient fluidity only at 180°C, while elastic deformations dominate at lower temperatures. The best quality of 3D printing is achieved using a composition based on a matrix of paraffin and PE (30 : 70), with a polyphenylene sulfone content of 40 vol %.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
