Molecular mass control in methacrylic copolymer latexes containing glycidyl methacrylate

Journal of Applied Polymer Science, 1996
Results are presented on the preparation and characterization of batch emulsion copolymers of butyl methacrylate and glycidyl methacrylate (GMA). The two main problems occurring during an emulsion copolymerization with GMA are partial hydrolysis of the epoxy groups and internal crosslinking of the latex particles formed. The influence of chain transfer

Preparation of amidoximated poly(glycidyl methacrylate) microbeads

Polymer International, 2010
AbstractPoly(glycidyl methacrylate) (PGMA) microbeads were synthesized by a simple suspension polymerization of glycidyl methacrylate and ethylene glycol dimethacrylate. The epoxy groups of the microbeads were firstly modified with 3,3′‐iminodipropionitrile (IDPN) and the resulting nitrile groups were then converted to amidoxime. From scanning electron

Polymerization and copolymerization of methacrylic esters derived from glycidyl methacrylate

Journal of Polymer Science Part A-1: Polymer Chemistry, 1968
AbstractCopolymerization of methacrylic esters derived from glycidyl methacrylate and nucleophiles with styrene was carried out. The monomer reactivity ratios of these methacrylic esters were varied with the alkoxy groups of the esters and the solvent used.

Reactive grafting of glycidyl methacrylate onto polypropylene

Journal of Applied Polymer Science, 2010
AbstractThis work explored the melt‐phase grafting of glycidyl methacrylate (GMA) onto polypropylene on a closely intermeshing corotating twin‐screw extruder (16‐mm screws, 40 : 1 length/diameter ratio). The modification of the base polypropylene to produce GMA‐grafted polypropylene was achieved via peroxide‐induced hydrogen abstraction from the ...

Novel fluorescent poly(glycidyl methacrylate) – Silica microspheres

European Polymer Journal, 2014
Abstract Monodisperse macroporous poly(glycidyl methacrylate) (PGMA) microspheres were prepared by multiple swelling polymerization using a modified Ugelstad method. The outer and inner parts of PGMA microspheres were coated with silica (SiO2) using tetramethyl othosilicate (TMOS) and trimethoxy(methyl)silane (TMMS) to produce PGMA&SiO2 and PGMA&Me ...

Melt Grafting of Glycidyl Methacrylate onto Polyethylene

International Polymer Processing, 1998
Abstract The melt grafting of Glycidyl Methacrylate (GMA) onto Polyethylene in the presence of free radical initiators was conducted in a co-rotating twin screw extruder. Reaction kinetic parameters for the overall grafting and homopolymerization reactions were estimated in a batch melt mixer.

Radical copolymerization of glycidyl methacrylate and carbonyl-containing phenyl methacrylates

Polymer Science Series B, 2011
New copolymers containing epoxide and carbonyl groups are synthesized through the free-radical copolymerization of glycidyl methacrylate with o- and p-formylphenyl methacrylates and o- and p-acetylphenyl methacrylates. It is demonstrated that the reactivity ratios and the yield of copolymers of ortho isomers of formyl and acetylphenyl methacrylates are

Synthesis and characterization of butyl acrylate/methyl methacrylate/glycidyl methacrylate latexes

Journal of Applied Polymer Science, 2009
AbstractThe butyl acrylate (BA)/methyl methacrylate (MMA), and glycidyl methacrylate (GMA) composite copolymer latex was synthesized by seeded emulsion polymerization technique taking poly(methyl methacrylate) (PMMA) latex as the seed. Four series of experiments were carried out by varying the ratio of BA : MMA (w/w) (i.e.

Dielectric behaviour of glycidyl methacrylatebutyl methacrylate copolymers

Journal of Materials Science, 1990
Different copolymers of glycidyl methacrylate and butyl methacrylate with various compositions have been prepared by free radical polymerization. The composition of these copolymers was determined by1H nuclear magnetic resonance technique. The dielectric properties of these compositions have been studied over a frequency range from 100 Hz to 50kHz and ...
