A series of nylon copolymers were synthesized and characterized based on the even-odd A-B monomer combination caprolactam and enantholactam. The nylon 6-co-nylon 7 samples displayed physical properties which directly correlate with copolymer composit

In this paper, we describe the thermal and spectroscopic analysis of oligo(thioethylene) model compounds for copolymers containing sequential thioethylene units. Many thioethylene copolymers and model compounds show multiple thermal transitions by DS

Samples of commercial nylon 7 were given different thermal or precipitation histories. Structure and crystallinity were followed by d.s.c., solid-state n.m.r. and attenuated total reflectance Fourier transform infra-red spectroscopy (ATR FT i.r.). He

Nylon 13,13 samples were prepared by various solvent-casting and thermal-treatment methods. Melt-quenched material showed broad, amorphous-like peaks in the X-ray powder pattern (at 2 θ = 21°, 4.2 A) and both the 13 C and 15 N solid-state n.m.r. sp

Solid-state 13C and 15N NMR spectroscopy, in conjunction with differential scanning calorimetry, wide-angle X-ray diffraction and infrared spectroscopy, were used to characterize a series of nylon 11 and 12 copolymers with mole percentages of nylon 1
