Chlorinated poly properties

Carbon Cha.in Backbone Polymers. These polymers may be represented by (4) and considered derivatives of polyethylene, where n is the degree of polymeriza tion and R is (an alkyl group or) a functional group hydrogen (polyethylene), methyl (polypropylene), carboxyl (poly(acryhc acid)), chlorine (poly(vinyl chloride)), phenyl (polystyrene) hydroxyl (poly(vinyl alcohol)), ester (poly(vinyl acetate)), nitrile (polyacrylonitrile), vinyl (polybutadiene), etc. The functional groups and the molecular weight of the polymers, control thek properties which vary in hydrophobicity, solubiUty characteristics, glass-transition temperature, and crystallinity. [Pg.478]

There has been considerable research on chlorine-resistant RO membranes (48—52). A poly(/n j -2,5 dimethyl)pipera2inthiofura2anainide used in the presence of low (3 mg/L) concentrations of chlorine resulted in a membrane life of three years (48). A copolyamide hoUow-fiber membrane for use in desalination has been developed that is resistant to 0.5 mg/L chlorine (49). Millipore Corporation has also developed a sulfonated polysulfone member that has desirable chlorine-resistance properties. [Pg.150]

Chlorinated vinyl chloride-based compositions composed from chlorinated poly(ethylene) and MMBS are suitable for injection molding products with good heat resistance, impact strength, mold-ability, and surface properties (20). [Pg.321]

Closely related to PVC, but with distinct properties of its own, is chlorinated poly(vinyl chloride) (CPVC), a polymer produced by postchlorination of PVC. The effect of adding more chlorine to the PVC molecule is to raise the Tg of the base resin to 115-135°C (239-275°F) range and the heat deflection temperature under load to around 115°C (239°F). CPVC also has higher tensile strength, higher modulus, and greater resistance to combustion and smoke generation. [Pg.404]

Chlorinated Poly(Vinyl Chloride). Post-chlorinated PVC combines the advantageous properties of PVC, e.g., good chemical and weather resistance with good solubility in most conventional solvents. Its importance has, however, continually decreased in the paints sector. [Pg.26]

The properties of chlorinated poly(vinyl chloride) of this type are in the main similar to those of unplasticized poly (vinyl chloride). (See Table 4.1 for some comparative properties.)

A blend of Hycar 1432 and chlorinated poly(4-methyl-l-pentene) in a ratio of 3 to 1 was found to give excellent adhesive properties for bonding a plasticized PVC sheet to steel. [Pg.214]

The properties of chlorinated poly(vinyl chloride) of this type are in the main similar to those of unplasticized poly(vinyl chloride). (See Table 4.1 for some comparative properties.) The most significant result of chlorination is the elevation of softening point, as a result of which the maximum service temperature is about 100°C compared to about 65°C for unplasticized poly(vinyl chloride). Chlorination also leads to a deterioration in heat stability and an increase in melt viscosity and thus chlorinated poly(vinyl chloride) is rather more difficult to process nevertheless, the material can be satisfactorily extruded and injeetion moulded. The major application for chlorinated poly(vinyl chloride) is in plumbing applications, particularly hot and cold water distribution and hot, corrosive effluent handling. [Pg.107]

The most chemical-resistant plastic commercially available today is tetrafluoroethylene or TFE (Teflon). This thermoplastic is practically unaffected by all alkahes and acids except fluorine and chlorine gas at elevated temperatures and molten metals. It retains its properties up to 260°C (500°F). Chlorotrifluoroethylene or CTFE (Kel-F, Plaskon) also possesses excellent corrosion resistance to almost all acids and alkalies up to 180°C (350°F). A Teflon derivative has been developed from the copolymerization of tetrafluoroethylene and hexafluoropropylene. This resin, FEP, has similar properties to TFE except that it is not recommended for continuous exposures at temperatures above 200°C (400°F). Also, FEP can be extruded on conventional extrusion equipment, while TFE parts must be made by comphcated powder-metallurgy techniques. Another version is poly-vinylidene fluoride, or PVF2 (Kynar), which has excellent resistance to alkahes and acids to 150°C (300°F). It can be extruded. A more recent development is a copolymer of CTFE and ethylene (Halar). This material has excellent resistance to strong inorganic acids, bases, and salts up to 150°C. It also can be extruded. [Pg.2457]

Some polymers consisting entirely of head-to-head placements have been deliberately synthesized to determine if significant property differences exist compared to the head-to-tail polymers. The synthetic approach involves an appropriate choice of monomer for the particular H-H polymer. For example, H-H poly(vinyl chloride) is obtained by chlorination of 1,4-poly-l,3-butadiene,... [Pg.204]
