Abstract
New siloxane-ester-containing chloro-maleimide polymers were synthesized by polycondensation reactions starting from various bis(dichloromaleimides) a nd bis(sebacomethyl)-tetramethyl-disiloxane sodium salt. The polymers' stru ctures were confirmed by IR and IH-NMR spectroscopy and by elemental analys is. The compounds were characterized by thermogravimetric analysis (TGA), g el permeation chromatography (GPC), solubility tests, and inherent viscosit y measurements. The polymers exhibited improved solubility in common organi c solvents (compared with the starting bismaleimides) and reasonable therma l stability.
