Chemical Reactions of Macromolecules in the Solid State,cations. Chemical transformations of solid high polymers are very often a part of the synthesis of a polymer with desirable final properties. Such type of reactions can be illustrated for example by the second condensation step in the synthesis of ladder-type thermostable polymers, in which the fina

In more modern times Prof. Staudinger is commonly acknowledged as the investigator most responsible for t

Polymers as Catalysts for Polymerization Reactions,n of N-carboxy-α-amino acid anhydrides (NCAs(I)).These monomers polymerize in the presence of bases with elimination of CO. and formation of poly α-amino acids; the reactions initiated by primary and secondary amines mainly follow the route shown in equation (1), although there are other processes occurring which need not concern us here.

Functionalization of Polymers,m, either in artificial or in biological systems. This definition is not absolute, since any chemical group may undergo chemical reactions. However, a polymer containing “reactive chemical groups” is usually prepared to be, and expected to act as a reactive substance and not merely as inert material.

Modification of Polymers Using Iodine Isocyanate. II. Improved Methods for Iodine Isocyanate Additiderivatives can be converted to methyl iodocarbamate or iodourea derivatives of polyisoprene by reaction with methanol or ammonia, respectively. The synthesis of a N′-(4-sulfonamidophenyl) iodourea derivative (a polyisoprene with pendant sulfanilamide groups) is described.

New Methods of Preparation of Tailor Made Polymer Networks,atories. However most of the experimental work was carried out on gels prepared either by polycondensation processes, or by radical copolymerization of two monomers one of which being bifunctional. The samples thus obtained are far from being structurally well defined for a number of reasons:
