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]

Cationic grafting from reactions have been performed by Kennedy, starting from backbones containing chlorine such as poly(vinyl chloride), poly(chloroprene-co-isoprene) and partially chlorinated styrene-butadiene rubber (SBR) and others. The grafting reaction involves monomers such as isobutene or styrene and it is generally initiated by means of diethylaluminum chloride (Scheme 19). [Pg.1178]

Butyl phenolic resin is a typical tackifier for solvent-borne polychloroprene adhesives. For these adhesives, rosin esters and coumarone-indene resins can also be used. For nitrile rubber adhesives, hydrogenated rosins and coumarone-indene resins can be used. For particular applications of both polychloroprene and nitrile rubber adhesives, chlorinated rubber can be added. Styrene-butadiene rubber adhesives use rosins, coumarone-indene, pinene-based resins and other aromatic resins. [Pg.597]

For the flame-retardance of styrene/butadiene rubbers (SBR), chlorinated paraffins with antimony trioxide, phosphoric ester plasticizers and alumina trihydrate filler are recommended. [Pg.390]

The fluorinated rubbers are exceptionally good for high-temperature service, but they are below silicones in this respect. They resist most of the lubricants, fuels, and hydraulic fluids encountered in aircraft a wide variety of chemicals, especially the corrosive variety and also most chlorinated solvents. They have good physical properties, somewhere near those of styrene butadiene rubber (SBR) at the higher hardness levels. FKM is valnable in automotive use for its extreme heat and oil resistance and is on a much higher level in this respect than the acrylic elastomers. It has weathering properties snperior to those of neoprene. However, fluoroelastomers are relatively expensive. [Pg.215]

Polystyrene resins are made from polymerized styrene and have good insulating power. Synthetic rubber, known as styrene-butadiene rubber or chlorinated rubber latex, can be used in paints for floor coverings or tank linings (Fischer and Adams 1990). [Pg.665]

Halogenated butyl rubber greatly extended the usefulness of butyl rubber by providing much higher vulcanization rates and improving the compatibility with highly unsaturated elastomers, such as natural rubber and styrene-butadiene rubber (SBR). These properties permitted the production of tubeless tires with chlorinated or brominated butyl innerliners. The retention of air pressure (5) and low intercarcass pressure (6) extended tire durability. [Pg.900]

Several strategies have been reported to improve the compatibility of NR/ EPDM blends, including the addition of a third component with low molar mass or a third polymer, sueh as polybutadiene (BR), styrene butadiene rubber (SBR), chlorinated rubber, chlorosulfonated PE or polyvinylchloride (PVQ, the incorporation of an accelerator moiety in the less unsaturated phase, and the functionalization of EPDM with maleic anhydride. ...

The chemical properties of the block copolymers are similar to those of unvulcanized styrene-butadiene rubber. Thus the block copolymers are soluble in a range of solvents, including chlorinated and aromatic hydrocarbons, esters and ketones. [Pg.439]

Chlorinated rubber floor paints are probably the most common of the lower-cost floor paints on the market. They produce tough and chemically resistant coatings, but their adhesion to concrete is not always good. They tend to wear off in patches and cannot be considered as a durable floor treatment except under light traffic conditions. However, re-coating is a simple job and floors can easily be repainted over weekend shutdowns, for example. Similar paints based on other resins such as acrylics, vinyls and styrene butadiene are also used. [Pg.103]

Acrylated rubber These are based on styrene butadiene and have become commercially available only relatively recently. They are manufactured in several grades but most have the advantage over other materials in this class of being based on white spirit solvent rather than the stronger and more obnoxious xylol. In other respects, they are similar to chlorinated rubber and cost approximately the same, although they are easier to airless spray and the dried film contains less pores. They are considered to have superior weather resistance to chlorinated rubber and vinyl. [Pg.128]

Green rubber is sometimes used as a primary or secondary binder in disk and drum formulations. Nitrile, styrene-butadiene and chlorinated rubbers have been used for this purpose. These rubbers are intimately mixed with curatives and other ingredients in intensive mixers. [Pg.1078]

Grafting from, exploits the active sites, which exist or can easily be generated on a polymer.
