Crosslinked polymer vs linear polymer

WebBecause the linear polymer exhibits high purity, it is less prone to absorbing moisture under high heat and humidity conditions compared to the cross-linked polymer. As a result, DIC.PPS product portfolio contains a wide variety of engineered products that can be custom formulated to meet the most demanding performance requirements. WebWhile linear polymers can be essentially characterized by the number of the monomer units, for branched and crosslinked systems e.g. the way of branching and their quantity is of significance for the polymer specific properties. In cases of crosslinked systems the molecular dimension is the macroscopic dimension of the sample. [Pg.102]
