摘要:

Some observations and techniques accepted as a matter of fact in industrial practice are not well known in academic circles. Some of these and their applications to research are summarized.

摘要:

Following the conclusion of the Characterization Section at the request of the Chairman, Prof. P. H. Geil, approximately 25 symposium attendees remained to discuss the general problem of morphology terminology for PVC. As a result the list of terms shown in Table 1 was developed. It is strongly recommended that future papers discussing PVC use these terms to permit common understanding of the morphological units being described.

摘要:

Enthalpy measurements by means of solution microcalorimetry were obtained on a PVC resin in the temperature range 37-110°C. Enthalpy measurements above Tgdetect a heat of fusion of about 1.5 cal/g of polymer and thereby demonstrate the presence of a soluble ordered structure in PVC. Enthalpy measurements on samples quenched and slow-cooled from within the temperature interval 37-220°C confirm the value of 1.5 cal/g for the heat of fusion as well as demonstrate a broad melting range of 130-200°C.
