Polymerization Reaction

A novel phosphorous-free terpolymer, used as a decalcifying agent for removing calcium from crude oil, was prepared through a free-radical polymerization reaction of acrylic acid, allylpolyethoxy amino carboxylate, and 2-hydroxyethyl acrylate.

Poly(acrylic acid) gels synthesized via free-radical polymerization of acrylic acid and high molarities of salt show properties quite different from such gels synthesized without salt. Enhanced properties include increased extensibility and modulus.

Temperature Sensitive

Novel chiral temperature-sensitive microgels based on N-isopropylacrylamide are reported in this paper. Such particles, poly (N-isopropylacrylamide-co-acrylic acid-L-phenylalanine ethyl ester)[ poly (NIPAM-co-ALPhe)], were prepared by free radical polymerization of NIPAM, chiral monomer ALPhe and crosslinker N,N,-methylene-bis (acrylamide). The microgels exhibit spherical shape and favorable monodispersity. Increasing the content of ALPhe units incorporated into the microgel network will increase the average diameter, but decrease the swelling ratios and the transition temperature of particles.

Organoplatinum(IV) complexes of general formula [PtXMe2R(NN)], containing vinyl substituents, have been prepared by oxidative addition of RX, (RX = methyl 2-(bromomethyl)acrylate, 2-(bromomethyl)acrylic acid, 2-bromoethyl methacrylate, acryloyl chloride, and chloromethylstyrene), to [PtMe2(NN)], NN = 2,2′-bipyridine or 4,4′-di-tert-butyl-2,2′-bipyridine. Polymers with organoplatinum(IV) substituents have been prepared either by free radical polymerization of the organoplatinum(IV) derivatized monomers or by free radical polymerization of the organic monomers, followed by the oxidative addition of the C-X substituents of these polymers to [PtMe2(NN)]. In the latter method, it is generally not possible to metallate all the C—X bonds, but a high degree of platinum incorporation can be achieved. Key words: organoplatinum, polymer, oxidative addition, vinyl.
