Dosage du PES (Plastifiant) d'une Resine BSL 914 (Repere CEAT C76) a Partir d'Etalons Divers (PES (Plasticizer) Levels of a BSL 914 Resin (CEAT C76 Reference) from Different Standards)

摘要

In light of the tests which are the subject of the technical note, the authors may assume that the various PES samples and all PES (polyether sulfone) contained in the different lots of Resin 914 analyzed at present have the same origin and demonstrate a characteristic CLHP peak. The first results given by the CEAT (PV No. 6977, Partial 1) are confirmed: The analytical method of CLHP of the PES in the special case of Resin 914 associated with an AS4 or T300 fiber seems therefore valuable: The absence of interaction fiber - PES allows putting PES in solution and subsequently its CLHP dosage.
