N- methacrylic

The attachment of iron chelating ligands to polymers is an alternative means of modifying bioavailability. DFB has been covalently bonded to poly(acrolein) and other synthetic polymers and shown to have some potential for use in extracorporeal detoxification of acute iron overloaded plasma (57). Poly(N-methacryl-oyl-6-alanine hydroxamic acid), a polydentate polymer obtained by derivatization of poly(acrylic acid) with pendant hydroxamic acid groups, has shown significant iron chelation activity in vivo (58), a result which is possibly related to the longer retention of polymeric species in the circulatory system.

Acryhc stmctural adhesives have been modified by elastomers in order to obtain a phase-separated, toughened system. A significant contribution in this technology has been made in which acryhc adhesives were modified by the addition of chlorosulfonated polyethylene to obtain a phase-separated stmctural adhesive (11). Such adhesives also contain methyl methacrylate, glacial methacrylic acid, and cross-linkers such as ethylene glycol dimethacrylate [97-90-5]. The polymerization initiation system, which includes cumene hydroperoxide, N,1S7-dimethyl- -toluidine, and saccharin, can be apphed to the adherend surface as a primer, or it can be formulated as the second part of a two-part adhesive. Modification of cyanoacrylates using elastomers has also been attempted copolymers of acrylonitrile, butadiene, and styrene ethylene copolymers with methylacrylate or copolymers of methacrylates with butadiene and styrene have been used. However, because of the extreme reactivity of the monomer, modification of cyanoacrylate adhesives is very difficult and material purity is essential in order to be able to modify the cyanoacrylate without causing premature reaction.
