Introduction to polymers

WebHigh molecular mass polymers often possess the best physical properties, which is why the most demanding uses of PP such as safety helmets and pipe fittings require low MFI grades. Beyond the standard grades are filled and special grades which use the basic range of polymers as a matrix for other materials, such as talc, mica and glass fibre, to modify … WebThe publication of the third edition of Introduction to polymers is an extremely timely, updated version of the second edition which was published some twenty years ago. This new edition has been expanded to reflect the extensive advances in polymer science in recent decades.
