摘要: The -13C NMR spectra of reductively dehalogenated samples poly(vinyl chloride) (PVC) have provided conclusive evidence for the presence 2,4-dichloron-butyl branches in original polymer. These are contained a-CHCl-CH2-CCl(CH2-CHCl-CH2-CH2Cl)-CH2-CHCl-arrangement which is formed as result a radical “backbiting” reaction. For series polymers prepared conventional ways at temperatures 43 to 100 °C, 2,4-dichloro-n-butyl branch concentration ranges from about 0.6 1.0/(1000 C).
