Scanning electrochemical microscopy (SECM) has been applied to polymethylmethacrylate, polystyrene and polyethylene glycol. Surface enhanced infrared reflection microscopy was applied to polyacrylonitrile, polybutadiene and styrene resins whilst Fourier transform infrared spectroscopy was applied to polyimides. Finally, nuclear magnetic resonance spectroscopy has been applied to the examination of the surfaces of films of polyethylene, Suryln and ethylene-vinyl acetate copolymer. ... [Pg.158]

Blends of polyethylene glycols having molecular weights of 1500 to 35,000 and poly(lactic acid) were studied with infrared spectroscopy and thermal analysis (227). When the blends contained more than 20 percent of either component, they could crystallize and consisted of two semimiscible crystalline phases that were dispersed in an amorphous phase. In blends containing less than 20 percent of either component, only the com-... [Pg.185]
