8. Chemical Methods in Polymer Physics

摘要: Publisher Summary This chapter discusses use of chemical methods in polymer physics. A number like plasma etching, halogenation, dehydrohalogenation, hydrolysis, and oxidation have been developed to study surfaces crystals. Halogenation dehydrohalogenation modify the crystal surfaces, while others hydrolysis cut folds removes amorphous surfaces. Physical methods, such as infrared spectroscopy, NMR, low wide-angle x-ray analysis, differential scanning calorimetry, gel permeation chromatography are employed analyze chemically treated Selective halogenation some useful applications apart from their analytical techniques. Regular block copolymers can be prepared by selective Certain properties flame, chemical, solvent resistivity, thermal stability, dyeability a increased halogenation. Long-chain dicarboxylic acids paraffins uniform molecular weight single The technique has also used location radiation-induced changes polymers.
