β¦ Synopsis
Copolymers of 2-hydroxyethyl-methacrylate, 2-hydroxypropyl-methacrylate, or 3-chloro-2-hydroxypropyl methacrylate with acrylamide or methacrylamide having different compositions were synthesized by free radical bulk polymerization. Some of their properties, for example, density, polymerization shrinkage, Vicat's softening point, glass transition temperature, hardness, and thermal and chemical stability were measured. The effect of the content of acrylamide or methacrylamide units on the properties of copolymers is discussed.

In order to calculate some kinetic parameters, such as the reactivity ratios, of the system β£-methylstyrene-methyl methacrylate, the bulk copolymerization of these two monomers with azobis isobutironitrile (AIBN) as a radical initiator was studied. Experiments were performed at the various temperatu
Tussah silk fibers were graft-copolymerized with methacrylamide (MAA) and 2-hydroxyethyl methacrylate (HEMA) in aqueous media, using a chemical redox system as an initiator. High weight gain values were obtained with both grafting agents (up to 175%). The extent of homopolymerization was negligible
The synthesis, characterization, and thermal properties of copolymers of methyl methacrylate (MMA) and N-(p-carboxyphenyl) methacrylamide/acrylamide (CPMA/CPA) are described. The copolymerization was carried out in solution by taking different mole fractions (0.1-0.5) of CPMA/CPA in the initial feed
## SYNOPSIS A series of novel superabsorbent copolymers of acrylamide (AM), sodium allylsulfonate (SAS), sodium acrylate (AA), and N,N'-methylenebisacrylamide (BisA) were synthesized using potassium persulfate (KPS)/N,N,N',N'-tertramethylethylenediamine (TMEDA) as the initiator. The influences of
