影響因子The first edition of this book (1958) described an analytical situation which had existed for a number of years for maintaining quality control on vulcanizates of natural rubber although the situation had recently been disturbed by the introduction of a range of synthetic rubbers which required identification and quantitative estimation. For the former purpose ‘wet‘ chemistry, based on various imperfectly understood organic reactions, was pressed into service. Alongside this was the first introduction of instrumental analysis, using the infrared spectra of either the polymers or, more usually, their pyrolytic products to ‘fingerprint‘ the material. The identification of a range of organic accelerators, antioxidants and their derivatives which had been intro- duced during the 1920s and 30s was, in the first edition, dealt with by a combination of column chromatography and infrared spectroscopy or by paper chromatography. Quantitative procedures were, however, still classical in the tradition of gravimetric or volumetric assays with an initially weighed sample yielding, after chemical manipulation, a carefully precipitated, dried and weighed end product, or a solution of known compos

Extraction,e diverse and complicated. As a first step it is advisable to differentiate between ., . and .. Extraction is here defined as the procedure for removing organic additives from the polymer/black/inorganic components without simultaneously removing significant amounts of the polymeric phase, whilst so

Inorganic fillers and trace metal analysis, sense this is of course true but in many cases merely weighing the residue yields insufficient information, and the ash is the starting material for further analyses, as in the determination of trace metals. In carrying out an ash determination on a compounded polymer the aim is to pyrolyse the pol

Formulation derivation and calculation,carried out. The major omission to date is the overall determination of polymer content. The purpose of this chapter is to fill this gap and to illustrate how the primary analytical data-that is, the results actually obtained-may be manipulated and correlated to provide the best estimate of the form

Validity of results, information in whatever form it may be required. During these manipulations the assumption has been made that the analytical result is exact. However, as is only too obvious to any analyst who carries out even duplicate analyses, any replication of an analytical measurement will, in general, give a
