Plasticized PVC and

Calcium—zinc stabilizers are used in both plasticized PVC and rigid PVC for food contact where it is desired to minimize taste and odor characteristics. AppHcations include meat wrap, water botdes, and medical uses. 

Extruded composites of plasticized PVC and short cellulose fibers have been investigated by Goettler [103]. Pronounced increases in tensile modulus, yield, and ultimate tensile strength are observed. Single step processing of reinforcement and polymer with good product performance are key characteristics of the material whose field of application lies in the vinyl hose industry. 

The effect of °Co y-ray irradiation on the mechanical properties, surface morphology, and fractography of blends of plasticized PVC and thermoplastic copolyester elastomer, Hytrel (E.I. Du Pont de Nemours Company, Inc., Wilmington, Delaware), have been studied by Thomas et al. [445]. Radiation has two major effects on the blend cross-linking of the Hytrel phase and degradation of PVC phase. Both effects are found more prominent at higher radiation dose. 

It appears that Charlton et al.94,95 have discovered the first methods for reversible and continuous optical measurement of the clinically highly important alkali and earth alkali ions. In one approach94 they use plasticized poly(vinyl chloride) along with valinomycin as the ion carrier, and a detection scheme that was later refered to as co-extraction. In their system, potassium ion is extracted into plasticized PVC, and the same quantity of the anionic red dye erythrosine is co-extracted into it. The extracted erythrosine is quantified via absorbance or reflectance. 

A number of standards are available for determining these properties. They relate both to the composition and the manufacture of the basic compounds of unplasticized and plasticized PVC and of PVC plastisols and the production of the individual test specimens as well as to the performance and evaluation of the tests [29-31],... 

P.R.48 4 does not bloom in plasticized PVC and is almost completely fast to bleeding. Its tinctorial strength in this medium is equally good. Desirable dielectric properties make P.R.48 4 a suitable candidate for use in PVC cable insulations. The pigment is also used for mass colored secondary acetate threads, fibers, and films wherever it meets the requirements for application. 

Benzimidazolone pigments, especially those covering the red range of the spectrum, were originally developed and used mostly for plastics. None of them were found to adversely affect the physical characteristics of their host medium. Benzimidazolone pigments do not bloom in plasticized PVC and other polymers. They are usually bleed resistant under typical application conditions. 

P.O.64 shows good migration resistance in plasticized PVC and exhibits medium tinctorial strength. The pigment is also used in polystyrene and similar polymers and is also recommended as a colorant for rubber. 

Typical applications are protective covers, tarpaulins, awnings, and chemical-protective garments.23 Thin THV films can be laminated onto temperature-sensitive substrates, such as plasticized PVC and polyester.24... 

This idea becomes even more pointed when we look at polymerization. Polyvinyl chloride is the familiar plastic PVC and is made by reaction of large numbers of monomeric vinyl chloride molecules. There is, of course, an enormous decrease in entropy in this reaction and any polymerization will not occur above a certain temperature. Some polymers can be depolymerized at high temperatures and this can be the basis for recycling, low... 

This reduces regularity/crystallinity (melting points 108-70°C), increasing softness/flexibility (modulus 138-19 MPa), transparency, and polar adhesion, again competing with plasticized PVC and thermoplastic elastomers, particularly in packaging film, coatings, and adhesives.

Example 1. A fine powder of poly(vinyl chloride) (10 g) and dioctylphthalate (10 g) are homogeneously mixed and cyclohexanone (30 ml) added to the plasticized poly(vinyl chloride). The mixture is heated to about 60 °C until it becomes transparent. Finely powdered cation exchange resin (particle size more than 200 mesh), three-to-seven times the weight of poly(vinyl chloride), is then added to the plasticized PVC and homogeneously mixed at 60-70 °C. The mixture is kneaded between rollers to make it homogeneous and to evaporate cyclohexanone, and then made into a film with rollers, and dioctylphthalate is extracted with methanol.23...

Immediately after its formation a polymer is most likely to find its properties changing at their most rapid rate, in the absence of specifically aggressive environments. Thus, plasticized PVC and vulcanized rubbers in particular are well known to change their properties... 

Pentaerythritol esters can be used instead of phthalic acid esters when low volatility is one of the major factors in the choice of plasticizer for PVC. Pentaerythriol triacrylate can be used to plasticize PVC and to produce-cross-links under UV radiation. Such plasticized cross-linked PVC has some application in the cable industry. 

Phosphorus-containing flame retardants are suitable for polar polymers such as PVC, but for polyolefins their action is not sufficient. In this case they are used together with Sb203 and with halogenated compounds. Alkyl-substituted aryl phosphates are incorporated into plasticized PVC and modified PPO (Noryl) to a great extent for other plastics they are less important. Quaternary phosphonium compounds are recommended as flame retardants for ABS and polyolefins.
