THE INFLUENCE OF HEAT TREATMENT ON STRUCTURES OF THE AGGREGATED STATE OF POLYAMIDE-1010*

Received Date: 8 May 1995

The structural parameters of the aggregated state of polyamide (PA)-1010 annealedat various temperatures were computed by means of the desmearing intensity from SmallAngle X-ray Scattering (SAXS) measurements and by using the concept of the distance dis-tribution function. The results indicated that the structural parameters of the aggregatedstate were strongly dependent upon heat treatment conditions and the maximum valuesof the structural parameters were obtained for the samples annealed at T = 175℃. The particle size Z annealed at different temperature was ranged between 8.1-12.8nm,and the values of the distance distribution function Pmax(Z)were obtained when Z=4.0-6.8nm.Using one dimension electron density correlation function (ID EDCF) method long period (L) and thickness of the lamellar(do)were estimated and were found to increase with the increase of the degree of crystallinity.
