“…Previous authors (6,7) had concluded that the polymer was composed entirely of the 1,4-structure. However, the spectrum which was reported (6) showed three strong resonances in the methylene proton resonance region between -1.05 and 1.10 6. It is felt that these are due to the contiguous methylenes of the 1,3-and 1,4-structures and possibly in part to the methylene proton of the ethyl substituent of the 1,4-structure.…”

Copolymers VI-252 G. References VI-253 A. INTRODUCTIONAmorphous (noncrystalline) polymeric solids are either glasses or rubbers. A glassy polymer lacks long range order, and is below the temperature at which molecular motions take place on the time scale of the experiment. A rubbery polymer is above the temperature at which molecular motions take place on the time scale of the experiment. The glass transition temperature, T g , is the critical temperature that separates glassy behavior from rubbery behavior. Many amorphous solids, including polymers, organic liquids, biomaterials, some metals and alloys, and inorganic oxide glasses, exhibit glass transition temperatures. The dramatic change in the local movement of polymer chains at T g leads to large changes in a host of physical properties. These properties include density, specific heat, mechanical modulus, mechanical energy absorption, dielectric coefficients, acoustical properties, viscosity, and the rate of gas or liquid diffusion through the polymer, to name a few. Any of these properties can be used, at least in a crude manner, to determine T g . References page VI -253 Specific volume Gl assCrystal l i zati on vol ume change Li qui d

The development of the polymer chemistry during the last decade is characterized by the existence of several new methods of polymerization, e. g. the isomerization polymerization of aliphatic hydrocarbons, the oxidative catalytic polymerization of aromatics, the photochemical polyaddition, the 1.3 and 1.4 dipolar polycycloadditions, the two step polycondensation processes. Some of these methods have already been applied on an industrial scale. Simultaneously new catalytic procedures were discovered, some of which permit stereoregular copolymerization, and very recently stereo-elective polymerization. These different aspects will be considered successively.The isomerization polymerization in which the chain growth is characterized by alternate addition isomerization steps, is illustrated by several examples, and compared to the polymerizations with previous monomer isomerization, as in the case of B-olehs.The stepwise oxidative coupling of different 2.6 disubstituted phenols, with oxygen in the presence of amine complexes of copper salts is considered from kinetic and structural point of view and compared with the oxidative FRIEDEL-CRAFTS reaction on aromatic hydrocarbons.Two types of photochemical polyadditions are considered on the basis of the cyclomerization reaction, in which cyclobutane rings are formed by dimerization of olefins (in solution and in the solid state), and of the reductive dimerization, e. g. of bisarylketones into polypinacols.
