Chlorobutyl rubber is prepared by chlorination of butyl rubber (chlorine content is about 1 wt%). This is a substitution reaction produced at the allylic position, so little carbon-carbon double unsaturation is lost. Therefore, chlorobutyl rubber has enhanced reactivity of the carbon-carbon double bonds and supplies additional reactive sites for cross-linking. Furthermore, enhanced adhesion is obtained to polar substrates and it can be blended with other, more unsaturated elastomers. [Pg.585]

Many other polymers compete with cellophane such as polyethylene which is extruded as a tough film or in greater thickness as a nonbreakable bottles. Vinyl products used in films are polystyrene, polyesters, and nylon. A chemical derivative from nature rubber, chlorinated rubber, gives films of extraordinary stretch ability. [Pg.271]

In 1942, various materials, such as resinous chlorinated paraffin, chlorinated rubber, chlorinated alkyd resins, and vinyl and vinylidene resins were unavailable for use in fire-retardant paints. Such chlorinated binders as were available were in critical demand for flameproofing fabrics. The present availability of such materials... [Pg.49]

Several examples of cationic grafting have been reported in the literature [40, 41]. Polymer chains having labile halogen atoms in combination with various Lewis acids have been used. Examples are polychloroprene, poly(vinyl chloride), chlorinated styrene-butadiene rubber, chlorinated PB, etc. The monomers involved in the grafting reaction include isobutylene, styrenes, THF, alkyl vinyl ethers, etc. [Pg.17]

Grafting from, exploits the active sites, which exist or can easily be generated on a polymer. Halogenated polymers are most frequently used for this purpose poly(vinyl) chloride), polychloroprene, chlorinated EPDM, chlorobutyl rubber, bromobutyl rubber, chlorinated polybutadiene, chlorinated butadiene-styrene copolymers etc.145).

As natural rubber is a product of nature, its properties are determined by the biochemical pathway by which the polymer is synthesized in the plant. In the case of natural rubber the polymerization process cannot be tailored like that of synthetic rubbers. The only option to modify natural rubber is after it has been harvested from the tree. The important modified forms of natural rubber include hydrogenated natural rubber, chlorinated natural rubber, hydro-halogenated natural rubber, cyclized natural rubber, depolymerised liquid natural rubber, resin modified natural rubber, poly(methyl methacrylate) grafted natural rubber, poly(styrene) grafted natural rubber, and epoxidized natural rubber [33,34]. Thermoplastic natural rubber prepared by blending natural rubber and PP is considered as a physically modified form of natural rubber. [Pg.424]

Dichloromethane [75-09-2] (methylene chloride) is a colorless, highly volatile, neutral liquid with a characteristic odor. It is insoluble in water but miscible with organic solvents. It has a very good solvency for many organic substances, such as fats, oils, waxes, and resins. Bitumen, rubber, chlorinated rubber, polystyrene, postchlorinated poly(vinyl chloride), vinyl chloride copolymers, polyacrylates, and cellulose esters are also soluble. The solubility spectrum can be expanded by adding other solvents. A mixture of methanol or ethanol and dichloromethane is a good solvent for cellulose ethers and acetyl cellulose. Cellulose nitrate is, however, insoluble. [Pg.352]

As in industry including butyl rubber chlorination and piperylene cationic oligomerization we often have to use liquid flows with different physical characteristics (density, viscosity) it is necessary to study the influence of these parameters on conditions of reaction plan front formation - quasi-plug-flow mode, and consequently on the effectiveness of external heat removal.

Since chemical reaction time is small (Tch = 6 sec) liquid-phase butyl rubber chlorination process in solution with molecular chlorine should be ascribed to novel class of chemical processes - fast chemical reactions that should be carried out also according with principally novel technology with the use of highly productive compact tubular turbulent apparatus of jet type.
