CRYSTAL STRUCTURE OF POLYPROPYLENE FILLED WITH RARE EARTH OXIDES

摘要

The weight ratio of isotactic polypropylene (iPP) and rare earth oxide (REO) in the samples was fixed as 100/1. The pure PP 1300. and filled PP's with Y_2O_5- Nd_2O_5 and Ho_2O_5 were coded as Sample 1,2,3 and 4. respectively.rnThe WAXD patterns are shown in Figure 1. There are two main parts of diffraction peaks coming from iPP and REO in every pattern. The typical feature of α-form crystal of iPP was observed in every sample.
