ABSTRACT

The molar mass distribution function and the polydispersity of polymers are important characteristics of synthetic polymers. They determine the mechanical, chemical and thermal properties of polymers. Plasma polymers consist normally of a soluble and an insoluble fraction [1]. The soluble fraction again can be divided in a lowmolar-mass fraction consisting of monomers, oligomers and cyclic components and a high-molar-mass fraction [2]. This broad molar mass distribution complicates any chromatographic analysis using gel permeation chromatography (GPC) or highperformance liquid chromatography. Ultra-high molar masses, strongly branched macromolecules and partially cross-linked aggregates (gel particles) may be better characterized using the method of field flow fractionation (FFF) [3].
