3D printing of reinforced polymeric materials, which provides products excellent physical and mechanical properties, is at the forefront interest in field additive technologies. To ensure material, time, financial savings, objects having reduced filling density are frequently prepared. The presented work aims to study effect different levels (18, 42, 62% using a honeycomb pattern) contrast 100% solid fill carbon fiber-reinforced polyamide 6.6 materials processed by Fused Filament Fabrication...
In this work, two bio-based raw materials, rapeseed oil and technical-grade oleic acid, were modified to yield acrylated monomers. Polymeric latexes designed for coating applications synthesized using emulsion polymerization. Methyl methacrylate butyl acrylate copolymerized with various ratios of the monomers (0–20 wt.% in monomer mixture). The polymerization high conversion low coagulum content was successfully performed up 15 monomers, leading long-term stable latexes. asymmetric flow...
This paper deals with the development of acrylic latexes providing high-performance water-resistant coatings. For this purpose, mutual effects anionic surfactant type (ordinary and polymerizable), covalent intra- and/or interparticle crosslinking (introduced by allyl methacrylate copolymerization keto-hydrazide reaction, respectively) ionic (provided nanostructured ZnO additive) were investigated. The prepared standard emulsion polymerization methyl methacrylate, butyl acrylate methacrylic...
Abstract The study is primarily focused on the possibility to utilize organic asymmetric flow field‐flow fractionation (A4F) coupled a multi‐angle light scattering (MALS) detector for characterization of copolymers methyl methacrylate with various acrylates prepared by emulsion polymerization. effects acrylate monomer type and content molar mass distribution degree branching acrylic have been studied A4F‐MALS using tetrahydrofuran as carrier solvent. It has found that growing amount results...
Abstract Acrylated methyl esters of higher fatty acids derived from camelina oil and linseed were synthesized through transesterification, epoxidation, subsequent acrylation. Methyl methacrylate butyl acrylate copolymerized with various amounts bio-based derivatives (5 – 30 wt% in monomer mixture) to obtain polymeric latexes for coating applications. Successful emulsion polymerizations up 25 the performed low coagulum (below 2%) high conversion (around 95%). The incorporation into was...
A water-based polymeric acrylate dispersion (latex) containing MgO nanoparticles, which had been added at a concentration of 1.5% (with respect to the monomers) during preparation procedure, was investigated as an environmentally friendly binder for sanitary interior paints. The properties this new latex were compared those reference system free magnesium synthesized by same route, i.e., semi-continuous emulsion polymerization. Tests made in order ascertain mechanical and chemical...
Epoxy resins are characterized by excellent properties such as chemical resistance, shape stability, hardness and heat but they present low flame resistance. In this work, the synthesized derivatives, namely hexacyclohexylamino-cyclotriphosphazene (HCACTP) novel diaminotetracyclohexylamino-cyclotriphosphazene (DTCATP), were applied curing agents for halogen-free retarding epoxy materials. The thermal combustion behavior of cured investigated. obtained results revealed that application both...
Common latex coatings suffer from poor water resistance, which often limits their practical application. This paper reports on the preparation of polyacrylate latexes using various approaches to tune wettability, and surface properties coating films. The mutual effects fluorinated monomer copolymerization, emulsifier type (polymerizable general), intra- or interparticle covalent crosslinking (due allyl methacrylate copolymerization a keto-hydrazide reaction, respectively) were studied....

The incorporation uncoated powder was performed during synthesis, using two-stage semi-continuous emulsion radical polymerization technique, obtain latexes...
Abstract Polyimides are a group of polymers with excellent thermal and mechanical properties. However, generally, they exhibit brown coloration due to charge transfer interactions between diamine donor dianhydride acceptor moieties. In this study, semi-alicyclic polyimides derived from cyclohexane tetracarboxylic 4,4′-oxydianiline were prepared using two-step method, where the imidization step proceeded via chemical route. The effects catalyst type (quinoline, triethylamine,...
