Ethylene Vinyl Acetate and its Acetoxy-Hydroxide Transformation, ethylene gas with vinyl acetate. They can be synthesised to contain only a few per cent by weight of the vinyl acetate comonomer or they can be produced with amounts of vinyl acetate well in excess of 50%. Those polymers with a low vinyl acetate content have properties closely related to those of a

ubject but an aspect which is often overlooked is the need to remove volatile matter during processing: for this reason we have included a chapter on devolatilisation. Current industrial practice is towards materials modification and this attitude is reflected in the chapters on the transformation of ethylene978-94-010-8358-4978-94-009-4183-0

Fatigue and Long Term Strength of Thermoplastics,nder cyclic loads. Hence the qualification implied within the title. At one time. these responses were known as static and dynamic fatigue, but this terminology led to some confusion with engineers. Consequently, as a matter of convention nowadays, the term ‘fatigue’ is restricted to the effects of

The new problems — although of course not completely new © refer mostly to rapid changes of inflationary pressure in a fully employed economy. Under these conditions the relatively large changes in absolute prices, price relations, wages and income distribution,
