The Wiener polymer index is a normalized Wiener index for infinite polymers defined as [Balaban, Balaban et al, 2001]... [Pg.594]

The choice of date range is arbitrary. The number of journal articles for each year was obtained from a search of electronic version of English-based polymer and polymer-related journals using the keywords polyolefin and blends. Within polyolefin keyword, the subkeywords used in the search were polyethylene (PE, LLDPE, LDPE, HDPE, UHMWPE, PE, etc.), polypropylene (PP, iPP, sPP, aPP, etc.), polybutene-1, poly-4-methylpentene-l, ethylene-diene monomer, ethylene-propylene-diene terpolymer, ethylene propylene rubber, thermoplastic olefins, natural rubber (NR), polybutadiene, polyisobutylene (PIB), polyisoprene, and polyolefin elastomer. For the polyolefin blends patent search, polymer indexing codes and manual codes were used to search for the patents in Derwent World Patent Index based on the above keywords listed in the search strategy. [Pg.10]

T. Ocher changes occur at this temperature that can be monitored to identify the T experimentally. These include changes in specific volume of the polymer, index of refraction, gas diffusion coefficients, thermal expansion coefficients (measured by dilatomeCry), and specific heat (measured by differential scanning calorimetry (DSC) or by differential thermal analysis (DTA)). General discussions of the elastic properties of polymers can be found in references (4.2)-... [Pg.224]

Provides access to chemical and chemically related patents. Subject indexing for each chemical patent from a controlled vocabulary designed to facilitate retrieval of chemical structures and polymers. Indexing is prepared from a review of the full text of patent documents 20 or more Uniterm codes are then added to each record. CLAIMS/UNITERM 1950-1970, File 223, parallels coverage of File 23, CLAIMS/CHEM 1950-1970 CLAIMS/UNITERM 1971-1977, File 224, parallels File 24, CLAIMS/U.S. PATENTS 1971-1977 and CLAIMS/ UNITERM 1978 to present. File 225, parallels File 25, CLAIMS/U.S. PATENT ABSTRACTS. [Pg.5]

On the other hand, when voltage is applied to the lens cell, the LC directors would be reoriented vertically following the electric field. Thus, the light would encounter ordinary refractive index, which is matched with the polymer index. As a result, the lenses are effectively switched off, and the displayed image is in 2-D mode. [Pg.551]

The activity Si of a component in a polymeric membrane can be described by Flory-Huggins thermodynamics [40]. Thus, the activity of a component (index i) in a polymer (index j) is given by... [Pg.329]

Equation (49) formulated for blends of linear macromolecules also provides the facility to model blends of linear polymers (index L) and branched polymers (index B) synthesized from the same monomer [28]. If the end-group effects and dissimilarities of the bi- and trifunctional monomers can be neglected, the parameter a becomes zero. This means that the integral interaction parameter is determined by the parameter i lb. i c > the conformational relaxation, in combination with the intramolecular interaction parameters of the blend components. Because of the low values of and the first terms in (47) and (48) can be neglected with respect to the second terms (for molar masses of the polymers that are not too low) so that one obtains the following expression ... [Pg.33]
