Abstract

The blend polyamide 1010/N,N′‐(diphenylmethane‐4,4′‐diyl)bismaleimide (PA1010/BMI) has been investigated by means of WAXD and SAXS. The results obtained with the help of the Ruland, variance and 1D EDCF analysis showed that the degree of crystallinity (W~c,x~) crystallite size (L~hkl~), long period (L) and thickness of average crystal lamellae (d) decrease with BMI content. Experimental and calculated density values (ρ~c~) are in good agreement. Addition of BMI to PA1010 causes an increase in structural distortion. The results from SAXS analysis also supported that a crystalline amorphous interphase exists in the lamellae of semicrystalline polymers, so that a three‐phase model instead of the traditional two‐phase model should be used.

Quinuclidine betaine (1-carboxymethyl-1-azabicyclo[2.2.2]octane inner salt, QNB) forms a complex with p-hydroxybenzoic acid (HBA) at the 1:1 ratio. The crystals are triclinic, space group P 1, with two symmetry non-equivalent QNBÁHBA complexes linked by a sequence of four O-HÁÁÁO hydrogen bonds into
