RUTHENIUM-CATALYZED COPOLYMERIZATION OF 2-ACETYLPHENANTHRENE AND ALPHA,OMEGA-DIENES - DIRECT SYNTHESIS OF COPOLYMERS WHICH REGULARLY INCORPORATE 2-ACETO-1,3-PHENANTHRENYLENE UNITS
Hj. Guo et al., RUTHENIUM-CATALYZED COPOLYMERIZATION OF 2-ACETYLPHENANTHRENE AND ALPHA,OMEGA-DIENES - DIRECT SYNTHESIS OF COPOLYMERS WHICH REGULARLY INCORPORATE 2-ACETO-1,3-PHENANTHRENYLENE UNITS, Polymer bulletin, 37(4), 1996, pp. 423-428
Copolymers with 2-aceto-1,3-phenanthrenylene units in the chain have b
een directly prepared by Ru catalyzed step-growth copolymerization of
2-acetyl phenanthrene and alpha,omega-dienes such as 1,3-divinyltetram
ethyldisiloxane. Copolymers which incorporate 2-aceto-1,3-phenanthreny
lene units possess higher T(g)s and increased thermal stability compar
ed to analogous copolymers which have 2-aceto-5-phenyl-1,3-phenylene(b
iphenyl) or 2-aceto-1,3-phenylene units. Fluorescence spectra of these
copolymers have been obtained.
