[交流] 绝版好书Handbook of Size Exclusion Chromatography

Handbook of Size Exclusion Chromatography
Preface
Molecular weight and molecular weight distribution are well known to affect the properties of
polymeric materials. Even though for decades viscosity has been an integral part of product
specifications used to characterize molecular weight of polymeric materials in industry, the need to
define the molecular weight distribution of a product has attracted little attention. However, in recent
years producers and users of polymeric materials have become ever more interested in value-added
polymers with not only specific molecular weights but also optimal molecular weight distribution to
offer unique performance advantages to products.
In fact, molecular weight distribution has become an important marketing feature for polymeric
products in the 1990s. It is very common these days to see new grades of polymeric materials
introduced to the marketplace that are specially designed to have either narrow or bimodal molecular
weight distribution. In the case of a copolymer, the stress is on the uniformity in composition
distribution throughout the entire molecular weight distribution. Therefore, the need to improve the
analytical capability in R&D to characterize molecular weight distribution by size exclusion
chromatography or gel permeation chromatography has become increasingly urgent in recent years.
Determination of molecular weight distribution of a polymer is very often not a simple task. This is one
of the reasons it is still not commonly used as a final product specification. Many books have been
published on size exclusion chromatography. However, there has still been a need for a book that
stresses practical applications of size exclusion chromatography to the important polymeric materials in
industry. Hopefully the valuable experiences of the authors in this book
很好的一本书哦,大家喜欢的话请支持哦!

和电视台收视率差不多。看上去有那么多人看,其实都是瞄一眼然后转台的
