Characterization methods for high temperature polymer blends

UTRACKI,formerly of the National Research Council, Canada [Pg.14]

Abstract This chapter provides information about characterization methods for examining the structure and properties of blends that contain at least one high temperature polymer. Methods are described that probe both the phase structure of such blends as well as techniques that define and measure the properties of blends. Relations between the determined phase structure and resultant properties are also discussed. [Pg.14]

Key words high temperature polymer blends, polymer blend degradation, polymer characterization, blending polymers. [Pg.14]

Dozens of blends are in the market. Since synergism is rare, new blends are designed by adding components to achieve the desired performance characteristics. Historically blend complexity has tended to increase for example, while initially two-component blends were sufficient (e.g., PPE -i-PS or HIPS) nowadays blends with seven polymers -i- compatibilizers are available (e.g., PPE -h PS or HIPS, PC, ASA, SAN, SEES and PTFEi ) or alternatively PPE with either PS, SEES or HIPS, PC, PEST, AES, PMMA and copolymer of alkyl and glycidyl methacrylate.
