摘要

Polymorphous i-PP containing a and β phases were studied by WAXD and computer peak-resolution method (CPRM). The asymmetric Gaussian-Cauchy functions (a-GC) were adoptedto fit the profiles of both amorphous and crystalline peaks. For the crystalline peaks

the fitting resultsof a-GC are better than the symmetric-GC; for the amorphous peaks

they are better than polynomialand exponential functions

etc. Using the retarded least-square procedure (RLSP) on microcom-puter the results of peak-resolution are rather satisfatory.For the polymorphous samples containing αand β phases

the relations between phase-state

crystallinity

crystalline size

the ratio of α

β relative content and the crystallization temperature Tc were studied by CPRM.The ratio of α

β relative contents obtained by CPRM and Turner-Jones eq have been carefully compared.There are many improvements in this work.A simple estimation method of WAXD peak areas

both for amorphous and crystalline peaks

is suggested.
