Zur Morphologie dünner PVC‐Filme

Acta Polymerica, 1984
AbstractDie Morphologie dünner PVC‐Filme, die durch Spreitung verdünnter PVC‐Lösungen in Cyclohexanon auf einem Gemisch Wasser—Methanol als Fällugsmittel hergestellt werden, hängt entscheidend von der Methanolkonzentration im Fällungsmittel ab: Oberhalb 19 Vol.‐% Methanol bilden sich globuläre Strukturen zwischen 20 bis 200 nm, unterhalb 17 Vol ...

Calendering of PVC: Defects in calendered PVC films and sheets

Journal of Macromolecular Science, Part B, 1977
Abstract Major types of defects appearing in calendered films and sheets are described. The conditions for the appearance of air bubbles and mattness were studied for the particular case of calendering crystal-clear, rigid, toughened PVC. A correlation was found between the presence of air bubbles in the film and a distribution of air inclusions in the

Study of discolouring change in PVC, plasticizer and plasticized PVC films

Polymer Degradation and Stability, 1997
Plasticized and non-plasticized PVC films discolour on photochemical attack. We have used UV analysis to study the separate contributions of PVC and plasticizer to discolouring in plasticized PVC. As has already been demonstrated, photochemical degradation leads to the browning of PVC films due to the formation of polyenes and the degradation is ...
