Synthesis and characterization of hydrophilic and spherical poly(glycerol dimethacrylate-co-glycerol-1,3-diglycerolate diacrylate) microbeads

Abstract

To cite this article: Erdal Uguzdogan (2013) Synthesis and characterization of hydrophilic and spherical poly(glycerol dimethacrylate-co-glycerol-1,3-diglycerolate diacrylate) microbeads, Designed Monomers and Polymers, 16:3, 250-262, DOI: 10.1080/15685551.2012 A new class of spherical and swellable microbeads was obtained by a newly proposed suspension polymerization protocol. Hydrophilic monomers in the form of crosslinking agent, glycerol dimethacrylate (GDMA), and glycerol 1,3-diglycerolate diacrylate (GDGDA) were copolymerized in an aqueous suspension medium. Poly(GDMA-co-GDGDA) microbeads were highly hydrophilic due to hydroxyl functionality from both crosslinking agents. In the proposed method, the organic phase including monomers and diluent (i.e. cyclohexanol) was dispersed in an aqueous medium by using poly(vinyl alcohol) as the stabilizer. Poly(GDMA-co-GDGDA) microbeads were obtained by changing GDMA/GDGDA ratio, monomer/diluent ratio, and stirring rate. The average size and size distribution properties, microbead yields, and the equilibrium swelling behavior of the gel beads were presented. Spherical and swellable bifunctional microbeads carrying hydroxyl-carboxyl or hydroxyl-amine groups were also obtained by including amine and carboxyl carrying functional monomers, 2-(dimethylamino)ethyl methacrylate, and methacrylic acid, respectively, in the suspension copolymerization proposed.

Copolymerization of cyclohexene-3-yl methyl methacrylate with styrene: synthesis, characterization, monomer reactivity ratios, and thermal properties

“…A substantial fraction of the methacrylate products are copolymers. [10][11][12][13] Polystyrene (PSt) is one of the world's most widely used polymers. The copolymers of styrene with (met)acrylates are very important to industry applications such as paints, adhesives, and coatings.…”
