Abstract Poly (amide-imide) s containing polybutadiene blocks were prepared by reaction of 4, 4'-methylenedi (phenyl isocyanate) with trimellitic anhydride and α, ω- diisocyanatopolybutadiene. The polymers were characterized by spectroscopic methods and X-ray diffraction. Incorporation of 5 wt.% of polybutadiene structures into polyimide decreases the temperature of 10% weight loss in nitrogen by 90 C. Glass transition ...
