Özet

The differences in the crystallinities of HDPE samples conditioned by three different procedures with different cooling rates were followed by use of FTIR, DSC and X-ray scattering techniques. From FTIR, relative values of crystallinities are obtained and if absolute values obtained from DSC and X-ray scattering are compared, the latter yielded higher values. All three groups of results showed the expected trend of increase of crystallinities with decrease of rate of cooling. (C) 1997 Elsevier Science Ltd.
