Waterborne hyperbranched alkyd-acrylic resin obtained by miniemulsion polymerization
(Polimeros, 2016-12-08)
Four waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by ...
Rheological, morphological, film and thermal properties of emulsions of polyvinyl acrylic resins, carboxymethyl cellulose and titanium oxide
(Journal of Physics: Conference Series, 2019-11-29)
The study of the physical-chemistry properties of dispersions are very importants in the coating industry, since of it depend the application and stability of these systems. Therefore, the aim of this investigation was ...
Colloidal, morphological, thermal, rheological, and film properties of waterborne hyperbranched alkyd¿acrylic resins
(Journal of Coatings Technology Research, 2019-04-23)
Waterborne hyperbranched alkyd–acrylic resins (HAAR) are interesting materials that provide excellent properties yet require only low levels of solvent in formulations using them. However, they have been scarcely studied. ...
Hyperbranched polyester polyol modified with polylactic acid as a compatibilizer for plasticized tapioca starch/polylactic acid blends
(Polimeros, 2018-03-15)
A hyperbranched polyester polyol of the second generation (HBP2) was modified with polylactic acid (HBP2-g-PLA) and employed as a compatibilizer for plasticized tapioca starch (TPS)/polylactic acid (PLA) blends. The effect ...
Structural, thermal, rheological, morphological and mechanical properties of polypropylene functionalized in molten state with maleinized hyperbranched polyol polyester
(European Polymer Journal, 2019-09)
In a previous study, we realized the functionalization of polypropylene (PP) with maleinized hyperbranched polyol polyester (MHBP) by using dicumyl peroxide (DCP) as an initiator for obtaining the PP-g-MHBPs. This process ...
Hyperbranched polyester polyol plasticized tapioca starch/low density polyethylene blends
(Polimeros, 2017)
In this work, low density polyethylene (LDPE)/plasticized starch (TPS) blends were prepared. The TPS employed in this study was obtained by plasticization of tapioca starch with a hyperbranched polyester polyol. Differential ...
Synthesis and characterization of the oxide nanoparticles obtained by the polymeric precursor method
(Journal of Physics: Conference Series, 2016-02-12)
Niobium pentoxide (Nb2O5) nanoparticles were prepared by the polymeric precursor method using citric acid as a chelating agent and ethylene glycol as a polymerizing agent. The powders obtained were characterized by X-ray ...
Effect of Calcination Temperature on the Behavior of the Agglomerated Co3O4 Nanoparticles Obtained Through the Sol–Gel Method
(Journal of Inorganic and Organometallic Polymers and Materials, 2020-07-31)
gglomerates of Co3O4 were obtained using the sol–gel method for the synthesis with subsequent calcination of the samples up to 550 °C. Through X-rays it was observed that the samples presented the pure spinel phase with a ...
Study of the structural, thermal, rheological and film properties of functional copolymers of hydroxyethyl acrylate and methyl methacrylate
(Polimeros, 2016-08-04)
New functional polymers will be prepared using alkyd resins having high solid content (environmentally friendly) and comb-type structural morphology. Different copolymers of hydroxyethyl acrylate and methyl methacrylate ...
Carbazole-Based Hyperbranched Polyester Polyol: Structural, Rheological, Thermal and Optical Properties
(Macromolecular Research, 2021-04-24)
The present study sought to obtain a hyperbranched polyester polyol derivative with fluorescent properties. Initially, a 4-((4-(9H-carbazol-9-yl)benzyl)oxy)-4-oxobut-2-enoic acid (CAV) was synthesized and esterified with ...
