Polyethylene-poly ethylene

The windows of the absorption cell are made from polymer material such as polyethylene, poly(ethylene terephthalate Terylene ) or polystyrene. [Pg.61]

Materials that typify thermoresponsive behavior are polyethylene—poly (ethylene glycol) copolymers that are used to functionalize the surfaces of polyethylene films (smart surfaces) (20). When the copolymer is immersed in water, the poly(ethylene glycol) functionaUties at the surfaces have solvation behavior similar to poly(ethylene glycol) itself. The abiUty to design a smart surface in these cases is based on the observed behavior of inverse temperature-dependent solubiUty of poly(alkene oxide)s in water. The behavior is used to produce surface-modified polymers that reversibly change their hydrophilicity and solvation with changes in temperatures. Similar behaviors have been observed as a function of changes in pH (21—24). [Pg.250]

Table 6 shows the sales estimates for principal film and sheet products for the year 1990 (14). Low density polyethylene films dominate the market in volume, followed by polystyrene and the vinyls. High density polyethylene, poly(ethylene terephthalate), and polypropylene are close in market share and complete the primary products. A number of specialty resins are used to produce 25,000—100,000 t of film or sheet, and then there are a large number of high priced, high performance materials that serve niche markets. The original clear film product, ceUophane, has faUen to about 25,000 t in the United States, with only one domestic producer. Table 7 Hsts some of the principal film and sheet material manufacturers in the United States. Table 6 shows the sales estimates for principal film and sheet products for the year 1990 (14).

Thin films of polyethylene, poly(ethylene-co-5-norbomen-2-yl acetate), and poly-(cthylene-co-5-norbomen-2-ol) were prepared on glass slides and contact angle measurements of water droplets determined. Testing results are provided in Table 2. [Pg.311]

The reaction of 9-anthrylcarbene with the polymers can affect the C-H bonds of various groupings of the macromolecules. Hence, if a predominantly identical structure of the bridge between the anthracene group and the poisoner chain is required, it is advisable to use the carbene method for bonding the LM to polymers with one type of C—H bonds (polyethylene, poly(ethylene oxide) etc.). [Pg.25]

Using a statistical-mechanical analysis, Pace and Datyner have estimated values of the model parameters. Semiquantitative agreement was obtained between solubility data generated from the model and experimental data for a number of simple gases in polyethylene, poly(ethylene terephthalate) and, to a lesser extent, for polystyrene. For polymers with flexible side groups, the agreement was only qualitative. [Pg.54]

Two examples of the use of localised thermal analysis are provided in order to illustrate the generic applications of this approach. Figure 8 shows localised thermomechanical analysis of the surface of the multi-layer film in Figure 4. Measurements were made at points within this image describing the bulk polymer, the central gas-barrier layer and the thin tie-layer between this and the bulk film. The melting transition temperatures are consistent with high density polyethylene, poly(ethylene-co-vinyl alcohol) and medium density polyethylene for the bulk, gas barrier and tie layers, respectively [101],... [Pg.72]
