Homopolymerizations methacrylamide

Our findings for both the copolymerization and the homopolymerization of acrylonitrile were thus unusually high, and the reason must be the emulsion polymerization process. The work of Joshi (12) on acrylamide and methacrylamide, which are water soluble, may be relevant. He reported values of 13.8 and 19.5 kcal/mole for acrylamide in hydrocarbon and in aqueous solution for methacrylamide the corresponding values were 8.4 and 13.4 kcal/mole... 

Other functionalized monomers that were polymerized by ATRP are shown in Table HI. Using ATRP, N-vinylpyrrolidone and hydroxypropyl methacrylamide were successfully homopolymerized when a cyclam was used as the ligand instead of bipy. Methyl aciylate and vinyl acetate were copolymerized and a random copolymer with narrow molecular weight distribution was obtained. Copolymerization of isobuter and acrylonitrile monomers was also successful to prepare alternating copolymers. M alternating copolymer was also obtained when styrene and N-(cyclohexyl)maleimide... 

It has been also reported sicne 1958 [52] that itaconic anhydride (lAn), which is an another cyclic derivative of lA, polymerizes as well as other lA derivatives, but its reactivity is less than those of RII and RPhll. Poly(IAn) may be derived into some poly(IA) derivatives by reaction with amines and alcohols [63,64]. The polymerization reactivities of several itaconamides (lAm) and itaconamates (lAE) were also investigated [48]. It was found that iV, -dialkyl substituted lAm homopolymerize in the presence of a radical initiator, but iV,iV,iVj -tetraalkyl-substituted one did not give a polymer, because the latter consists of an a,7V, trisubsti-tuted acrylamide structure resemble to, y disubstituted methacrylamides. Similar results were obtained for polymerization of mono- and, V disub-stituted lAE. 

For phosphonated bis(methacrylamide)s, thermal homopolymerization of monomers (3) (Scheme 2.2) in bulk and in solution using AIBN at 80 °C resulted in crosslinked polymers. On the other hand, copolymerization with 2-(2-carbo)yallyloxymethyl)acrylic acid led to soluble polymers, obtained at low monomer and initiator concentrations. Molecular weights varied between 13 000 and 49 000 g mol . Thermal copolymerization of phosphonic acid derivatives (monomers 4) was carried out (i) with acrylamide in water at 65 °C using V-50 as initiator or (ii) with HEMA in ethanol at 50 °C. Cross-linked polymers were obtained in both cases. 

A method for the preparation of ferrocene-functionalized acrylate and methacrylate monomers as well as their homopolymerization and copolymerization leactions " was repeated in 2002. Using AIBN as a radical initiator, polyferro-cenylethyl acrylate, methacrylate, acrylamide, and methacrylamide were synthesized, as shown in scheme 5.
