Series of emulsion lattices having different composition ratios of styrene/butyl acrylate (St/BuA) as base monomers in conjunction with acrylic acid (AA) and/or methacrylic (MAA) were prepared and characterized. The preparation was carried out in industrial scale in semi batch reactor at pH range of 3-5 using potassium persulphate (KPS) as an initiator, sodium luaryl sulphate (SLS) as an emulsi...

Emulsion polymerization is considered a safe, economic, versatile, and consequently of interest as an environmentally friendly process. However , surfactants utilized need to be biodegradable , and still guarantee a good film quality , with an adequate performance according to its end use. We investigated the substitution of an alkyl phenol ethoxylated (APE) surfactant ,commonly for a sulfosucc...

To develop a platform for tumor chemotherapy, poly(acrylic acid-co-methyl methacrylate) microparticles have been synthesized. Carboxylate containing monomers were included to complex therapeutic agents, specifically cisplatin. Microparticles were prepared by free radical emulsion polymerization in aqueous media. Particle diameter, zeta-potential, in vitro cytotoxicity, and in vivo acute toxicit...

Maxillofacial prostheses is a dental medicine specialty aimed at restoring anatomical facial defects caused by cancer, trauma or congenital malformations through an artificial device, which is commonly attached to the skin with the help of an adhesive. The purpose of our research was to develop a pressure-sensitive adhesive (PSA) based on acrylic monomers, characterizing and determining its dry...

Objective of present study involves preparation and evaluation of floating microballoons of indometacin as a model drug, to increase its residence time in the stomach without contact with the mucosa. The microballoons were prepared by the emulsion solvent diffusion technique using different ratio of acrylic polymers (Eudragit RS100 and Eudragit S 100) as carriers. The yield of microballoons was...

The efficient synthesis of all-acrylic, film-forming, core-shell colloidal nanocomposite particles via in situ aqueous emulsion copolymerization of methyl methacrylate with n-butyl acrylate in the presence of a glycerol-functionalized ultrafine silica sol using a cationic azo initiator at 60 °C is reported. It is shown that relatively monodisperse nanocomposite particles can be produced with ty...

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 conten...

This article describes the magnetically responsive microgel that consists of a small iron oxide magnetic nanoparticles (∼15 nm in diameter) embedded in a biocompatible microgel varying from ∼65 to ∼110 nm in diameter. These systems show great promise as active component of microscale and nanoscle devices and are expected to have wide applicability in various biomedical applications. Polymeric m...

In this study, ‘Hanfu’ apple trees were used as a test material to determine the effect of a functional protective film on the ability of the trees to withstand temperatures below zero. The functional protective film is a quaternary copolymer prepared by emulsion polymerization of vinyl acetate (Vac), butyl acrylate (NbA), methyl methacrylate (MMA) and acrylic acid (AA). The resulting copolymer...
