Methacryl amide

Acrylamide is the most important and the simplest of the acrylic and methacrylic amides. Acrylamide is a colorless crystalline solid. The basic physical properties and solubilities of acrylamide are given in Table I. Acrylamide is a severe neurotoxin and is a cumulative toxicological hazard. 

Some optically active N-substituted poly-acryl and poly-methacryl amides were prepared mostly by radical polymerization (Table 20). 

Upon vibratory milling, acryl and methacryl amides give anion radicals that are key species in the reaction (Simonescu et al. 1983) ... 

Further growth of the polymeric chain proceeds in the usual manner. Compared to the polymeric materials obtained via conventional methods, the mechanochemically synthesized polyacryl and polymethacryl amides have lower molecular weights (Simonescu et al. 1983). Acrylonitrile, styrene, e-caprolactam, isoprene as well as aryl- and methacryl amides have a special optimal duration of the polymerization upon grinding (Oprea Popa 1980). In the case of the aryl- and metacrylamides, the polymerization proceeds slowly, usually between 24 and 72 hr. After that, some acceleration takes place and the process is completed within 96 hr (total). 

Recently, further synthetic polymers have been proposed as plasma substitutes. Thus, Kopecek and Bazilova (56) examined poly[N-(2-hydroxypropyl)methacryl-amide] [22].

Investigations on the spacer function and the cleavabflity of the substrate from water-soluble copolymeric enzymes based on poly[N-(2-hydroxypropyl)methacryl-amide] were carried out by Kopecek and coworkers These studies reveal that there is no simple relationship between the length of the spacer and the cleava-bility of the substrate. It has also been observed that the length and the type of the spacer allows the kinetics of the cleavage to be controlled.

Oligopeptide sequences can be incorporated into N-(2-hydroxypropyl)methacryl-amide copolymers (for the different methods used see section 2) which serve as potential drug attachment/release sites and experiments have been carried out to investigate whether such sequences could be efficiently cleaved by lysosomal enzymes. 

Oxazoline Derivatives. Oxazolines are of great interest because of their ability to undergo cationic ring-opening poljunerization. In this connection, the functionalized monomers A(-[4-(4, 5 -dihydrooxazol-2-yl)phenyl]acryl amide (5a), A -[4-(4, 5 -dihydrooxazol-2-yl)phenyl]-2-methacryl amide (5b), N- 10-[4-(4, 5-dihydrooxazol-2-yl)phenylcarbamoyl]decyl -2-acryl amide (6a),... 

The synthesis of the diazosulfonate terpolymer via free radical terpolymerization is described in ref. 10. Amino terpolymers were synthesized by free radical polymerization of the three monomers MMA, 3-(triethoxysilyl)propylmethacrylate and the N-NVOC-aminopropyl-methacryl-amide (equimolar amounts) in dioxane at 75°C for 70 h as described in ref. 11. The protection of the amino monomer has been carried out according to the literature (12).

Preparation of PNiPAM, other polyacrylamide derivatives and molecular weight fractionation PNiPAM and other polyacrylamide derivatives were prepared by conventional free-radical polymerization of purified monomer which was synthesized by the reaction of acrylic or methacrylic acid chloride with the equivalent amount of monoamine compound to give the corresponding N-substituted acryl- or methacryl-amide derivatives. Most of the polymers were fractionated from ca.1% dry acetone solution by n-hexane as the precipitant at room temperatures ),... 

To prevent losses of antioxidants through volatilisation or extraction, Kline and Miller have proposed the use of antioxidants which copolymerise with butadiene and styrene or butadiene and acrylonitrile. They draw particular attention to N-(4-anilinophenyl) methacrylic amide, which is used for a number of special grades.
