The kinetics of excimer formation and decay in dilute dichloromethane solutions of poly(Nvinyl carbazole) have been investigated using time-resolved fluorescence spectroscopy. Further evidence for dual excimer formation in this polymer is presented; interconversion of the excimeric states appears to

Abstraet--Carbazole units in copolymers can be cross-linked by reaction with a Lewis acid catalyst in methylene chloride. The reaction initially causes gel formation, followed by the development (with BF3. Et20) of a characteristic blue colour. The blue product has been shown to be a cationic dye of
## Abstract Styreneโacrylonitrile (SAN) with acrylonitrile (AN) concentrations of 11.6โ26 wt % and ฮฑโmethylstyrene acrylonitrile (ฮฑMSAN) with a wide range of AN concentrations are miscible with poly(vinyl chloride) (PVC) through solution blending. Here we examine the rheological properties and misc
