Plasmamodifizierung von Polymeroberflächen. III. Gasphasenpfropfung von Acrylsäure auf Polyethylenterephthalat

Abstract

Die Ergebnisse mikrogravimetrischer Untersuchungen zur Plasma-initiierten Gasphasenpfropfung von Polyethylenterephthalat-Oberflachen (textile Flachengebilde, Folien) mit Acrylsaure werden dargestellt. Der Pfropfgrad wird in Abhangigkeit von den Aktivierungs-und Pfropfbedingungen bestimmt. Die qualitative und quantitative Auswertung gestattet Aussagen uber den Mechanismus und die Kinetik der Pfropfpolymerisation. II~za3,nennoe aodu$uyupoeanue nosepxnocmu noawepoe. I I I .

Plasmamodification of polymer surfaces. I I I . Gas phase grafting of acrylic acid on poZy(ethyZene terephthalate)Results of microgravimetric measurements of plasma-initiated gas phase grafting of acrylic acid on poly(ethy1ene terephthalate) surfaces (textiles and films) are described. The degree of grafting is determined in dependence on activation and graft parameters. The qualitative and quantitative interpretation provides information on mechanism and kinetics of graft polymerization. npHBOAfXTCR pe3yJIbTaTk.l MHKpOrpaBMMeTpHgeCKX MCCJIeAOBaAMfi ra3O@l3HOfi IIPHBHBKH aKpHJIOBOfi KHCJIOTbI,

An Introduction to Plasma Polymerization

“…Thus the grafting of acrylic acid to various polymers was reported by Bradley [204]. The grafting of acrylic acid onto poly(ethylene terephthalate) after plasma treatment was studied in detail by Meichsner and Poll [206]. Vinyl acetate, vinylidene chloride and allyl bromide were also shown to graft in this fashion.…”

In Situ Characterisation of Polymer Surfaces and Thin Organic Films in Plasma Processing

“…For investigation of plasma polymer modification the polymer film must be deposited on the crystal plate by dip or spin coating procedures. In this paper the microgravimetric investigations are carried out by means of an electronic vacuum microbalance (SARTORIUS) which is integrated into the plasma chamber [19]. The advantage of this method is that no special sample preparation is needed.…”
