Oligo blends

Examples of known phosphazene polymer blends are those in which phosphazenes with methylamino, trifluoroethoxy, phenoxy, or oligo-ethyleneoxy side groups form blends with poly(vinyl chloride), polystyrene, poly(methyl methacrylate), or polyethylene oxide).97 100 IPNs have been produced from [NP(OCH2CH2OCH2CH2OCH3)2] (MEEP) and poly(methyl methacrylate).101-103 In addition, a special type of IPN has been reported in which a water-soluble polyphosphazene such as MEEP forms an IPN with a silicate or titanate network generated by hydrolysis of tetraethoxysilane or tetraalkoxytitanane.104 These materials are polyphosphazene/ceramic composites, which have been described as suitable materials for the preparation of antistatic layers in the manufacture of photographic film.

The hght scattering in both the parallel (Vv) and cross polarization (Hv) modes, was measured for PP/partiaUy hydrogenated oligo(styrene-co-indene) blends. The results indicated that the primary lamellae (thick line in Figure 8.13b) sufficiently grew in the...

Three different series of binary blends were prepared by mixing hydrogenated oligo (cyclopentadiene) (HOCP), isotactic polypropylene (iPP), and poly(l-butene) (PB-1), alternatively. The influence of the presence of HOCP, on the morphology, crystallization, melting behavior, and supermolecular structure of...

Fig. 3. Strand displacement assay. Polymerization reactions were performed at 68° as described in the text using f Turbo (lanes 3,4), lyu (lane 5), or Taq (lane 6) DNA polymerase. (Stratagene s PfuTurbo DNA polymerase is a blend of cloned Pfu DNA polymerase and a proprietary PCR enhancing factor.) The blocking oligo was added to reactions shown in lanes 4-6. Lane 1 shows the radiolabeled 20 bp size marker (two bands are resolved on the denaturing gel for each size marker), while lane 2 is a no enzyme (template only) control.

Cyano-substituted oligo(phenylenevinylene) dyes that are able to form excimers with terminal alkyl tails have been blended with fluorinated host polymers [163] that have a different crystallinity. 

Solid polymer electrolytes have been actively pursued as a major contribution to the development of high-energy density batteries, particularly lithium secondary batteries. The poly(p-phenylene)s substituted with oligo(oxymethylene) side chains and blends of these novel polymers with lithium salts are achieved by biaryl coupling of benzene-1,4-diboronic acids (Fig. 4). ° OctapoIy(p-phenylene) functions as the artificial ion channel which specially recognizes (bio)membranes by their thickness (Fig. 5). ...

The concept of norbomene-terminated oligo-imides was further studied at the NASA Lewis Research Center by researchers who developed the polymerization of monomeric reactants (PMR) approach. The method, represented in Fig. 9.18, involves a blend of both the dimethyl ester of 3,3 -benzophenonetetracarboxylic acid 42 and the mono-methylester of 5-norbomene-2,3-dicarboxylic acid 41 with 4,4 -methylenebisbenzeneamine 34 in solution in methanol.
