Molecular weight, retention

Mass chromatography, by virtue of providing molecular weight, retention time, and quantitative analysis, is widely applicable to solving analytical problems. Some categories of application are summarized in the following paragraphs. [Pg.76]

A simple but elegant example of the broad utility of mass chromatography is shown in Figure 6. In this case, a polymer sample was thermally decomposed at 400°C, and the products were analyzed. The molecular weight, retention time, and quantitative analyses of the major products indicated that the sample was a 69% methyl methacrylate-31% styrene copolymer. [Pg.78]

HDPE after four years at this temperature exhibited no change in both elongation retention and molecular weight retention. [Pg.241]

A trialkyl phosphite. It can be used in acrylics to iaqprove color euid molecular weight retention during processing. It also provides stability to nylon, unsaturated polyester, and PVC. When Weston TIOP phosphite is used in lubricants, it functions as a sulfur deactivator. It can also be used to improve antifriction and antiwear characteristics. [Pg.92]
