A reexamination of previous studies concerning the electrical (‘corona’) discharge treatment of polyethylene and the resulting enhancement of autoadhesion has been carried out. X-ray photoelectron spectroscopic data provide new insight into the p

Infra-red spectra of isotactic polypropylene samples having different crystallinity have been observed in the range 400 to 10cm−1. Eleven bands have been identified, whereas only eight internal modes are predicted for this region on the basis of li

Polarized infra-red (i.r.) spectroscopy has been used to study the changes in molecular orientation and conformation which occur on drawing poly(ethylene terephthalate) sheets. The i.r. data provided orientation functions 〈P2(θ)〉ir where θ is t

Some 30°C below the melting point in annealed samples of highly crystalline polypropylene, considerable changes occur in the coefficient of linear expansion and in a wide variety of temperature derivatives of spectroscopic features. It is shown that

Infra-red spectra of isotactic polybut-1-ene samples in crystalline modifications I (3 1 helix) and II (distorted 11 3 helix) have been obtained for samples of different crystallinity, at temperatures as low as 30K. The spectrum of form I is remarkab

Experimental data are provided on the molecular structure of paracrystalline samples of quenched melts (glasses). We propose that rods of helical molecules are present in the ‘glasses’, their length being sensitive to the temperature of the melt

The laser-Raman spectrum of poly(methyl methacrylate) complete with depolarization data is reported. A spectrum of powdered poly(ethyl meth-acrylate) is also given for reference purposes. Infra-red data on these polymers are included. The spectral da

A new method which provides a rapid and reproducible quantitative determination of the alcoholic -OH and the carboxylic -OH end-group content of poly(ethylene terephthalate) film is described. The method is based on existing infra-red spectroscopic t

The use of near-infrared Fourier transform Raman spectroscopy in the analysis of polypeptides is critically reviewed. A range of peptides and polypeptides are discussed and show promising results in the pure crystalline form. However, in aqueous solu
