Polymer Technology
All thermoplastic, thermosetting & elastic materials can be processed in a extrusion machine, however it can not be used for the production of plastic
Swelling tendency or solubility of polymers in a particular solvent decreases with increase in molecular weight of the solvent
High molecul ar weight polymers on dissolving gives solution of very low viscosity
Greater the degree of cross-linking in the polymer, lesser is its solubility
Polymers having more aliphatic character are more soluble in aliphatic solvents, while those polymers having more aromatic character are more soluble in aromatic solvents
