ABSTRACT
The emphasis in research and technological development of new products in the polymer industry has changed from synthesis of novel monomers to blending polymers in order to obtain desirable performance properties at a dial-in cost. Polymer blends offer improved performance/cost ratios and ®exibility to tailor-make the product to suit customer needs. Polymer blends are intimate mixtures of two or more polymers. The individual components may be melt-mixed, solution blended, co-precipitated, controlled devolatilized, or coagulated before ™nal processing. Finished articles are converted from blends by extrusion or molding processing operations.
