An important characteristic of a resin is the speed with which the polymer can be processed with the plasticizer in the plant, or its dryblending characteristics. The dryblending behavior of the polymer is dependent upon its microstructure and macrostructure. It is well known that some degree of porosity is required in order to obtain good dryblending properties; however, there are also other factors which affect the dryblending. Another factor, which is defined as the Swelling Index, is identified, and the use of this to help characterize dryblending behavior of different resins is discussed.
