Photoredox reaction of functionalized polyelectrolytes

01-Jan-1986 | Morishima, Yotaro; Nozakura, Shun‐Ichi, Journal of Polymer Science: Polymer Symposia, 1986

Abstract The electron transfer reaction from excited phenanthrene to acceptors was shown to be modified markedly when the phenanthrene unit was covalently linked to polyelectrolytes. (1) Such functionalized polyelectrolytes were shown to form hydrophobic microdomains in aqueous solution. (2) ...

Polyetherimides. II. High‐temperature solution polymerization

01-Jan-1986 | Takekoshi, T.; Kochanowski, J. E.; Manello, J. S.; Webber, M. J., Journal of Polymer Science: Polymer Symposia, 1986

Abstract The polymerization and characterization of the ether‐containing aromatic polyimides of the following general structure are presented. The polymerization was conducted in one step in homogeneous solution of m‐cresol at high temperatures. Typical polyeterimides (PEI) were ...

Synthesis and characterization of main‐chain polyaminimides

01-Jan-1986 | Salamone, J. C.; Richard, R. E.; Watterson, A. C., Journal of Polymer Science: Polymer Symposia, 1986

Abstract Three novel main‐chain polyarninimides were prepared containing rigid and/or flexible groups within the backbone. The polymer precursors were initially synthesized from bis‐dimethylhydrazides and dihalides at room temperature through the Menschulkin reaction, which yielded hydrazinium ...

Determination of polymer‐polymer interaction parameters of incompatible monodisperse and polydisperse polymers in solution

01-Jan-1986 | Narasimhan, Venkataraman; Huang, Robert Y. M.; Burns, Charles M., Journal of Polymer Science: Polymer Symposia, 1986

Abstract Equilibrium phase studies were carried out on the ternary system of polystyrene‐poly butadiene‐toluene at 23°C and 1 atm. Narrow and broad molecular weight distribution (MWD) samples of polystyrene and polybutadiene were employed, and their binodal curves were established. Expressions ...
