Physical properties of monomers

To the author s knowledge, data on all physical properties of monomers have not been collected in a single treatise. The existing sources are limited to the basic data and the remaining information has to be sought in original articles. Some values of physical properties are summarized in Table 4. If more detailed data are needed in the following text, they will be included at the appropriate place.

Physical Properties of Monomers. 1-Butene [106-98-9] is a colorless, flammable, noncorrosive gas its physical properties are fisted in Table 1, and its thermodynamic properties are available (16). Because 1-butene has a very low flash point, it poses a strong fire and explosion hazard. 

Table II gives some of the physical properties of monomer A -vinyl-pyrrolidone.

Polymerization depends primarily on the chemical and physical properties of monomer. First, the monomer must be sufficiently reactive for radical polymerization. Vinyl acetate failed to polymerize during mastication as a result of the apparent low reactivity of alkyl radicals toward this monomer [86, 88], whereas isoprene, vinyl chloride, and butadiene also had only a low reactivity [88, 95], It has been claimed that results with vinyl acetate result from traces of impurities including oxygen [98]. Gelation occurs on mastication with monomers, which give radicals sufficiently active to react with low-activity groups in natural rubber. The effect of monomer composition... 

In recent years, this section of this report has been dominated by the photochemical and photophysical properties of Re(CO)3(diimine)X complexes. Although the main deluge of research is over, there are still examples to be found. The photochemical/physical properties of monomer and polymer species with ReI(CO)3(phen) chromophores has been investigated by Wolcan and Ferraudi, and proton-controlled photoisomerisation of rhenium(I) tricarbonyl bipyridine linked to amine or azacrown ether groups by a styryl pyridine bridging ligand has been discovered by Perutz et alP...
