There are two distinct types of silica resins. Totally porous resins have a quaternary ammonium functional group chemically attached. Their particle size is in the range of 3 pm to 10 pm with typical exchange capacities of 0.1 to 0.3 mequiv/g. Pellicular materials have a larger particle size and are covered with a thin layer of a polymer with quaternary ammonium groups. For example, Zipax SAX is covered with a layer of lauryl methacrylate 1 pm to 3 pm thick. [Pg.51]

On the other hand, the polymerization reaction and the adopted process parameters affect typical macromolecular characteristics such as average molecular weight, molecular weight distribution, stereoregularity, chemical composition and sequence distribution in copolymers. For the synthesis of macromolecules bearing specific functional groups, chemical modification of preformed macromolecules can also be carried out... [Pg.525]
