Phosphole copolymers

Biphenyl-phosphole copolymer 65 is isolated as an air-stable and soluble powder exhibiting a rather high molecular weight (Mw = 16 000 Mn = 6200) according to gel permeation chromatographic (GPC) analysis. Although multinuclear magnetic resonance spectroscopy and elemental analysis support the proposed structure, the presence of a small number of diene defects is very likely. Polymer 65... [Pg.140]

One remarkable example of the reactivity of a phosphole P-substituent is the radical copolymerization of dithienophosphole 146 with styrene using 2,2,6,6-tetramethylpiperidinyl-l-oxy (TEMPO) as the initiator (Scheme 42) <2004AGE6197>. Copolymers 48 are high molecular weight materials with relatively narrow poly-dispersities. They have been characterized by H, and P NMR spectroscopy. [Pg.1084]
