| Özet |
| AbstractSilicone‐based amphiphilic surfactants were synthesized as anti‐foaming agents through a polycondensation reaction between chlorine‐terminated polysiloxane and polyethers. Poly(ethylene glycol) (PEG) and poly(propylene glycol) of different molecular weights were used. The structures of these tri‐block co‐polymers were characterized by FTIR, 1H NMR and ESI–MS analysis. Surface tension, foam height and foam destruction properties of these co‐polymers were determined. Spectroscopic analysis confirmed that bonding of polyether to polysiloxane was successful and two types of different tri‐block co‐polymers were obtained. The anti‐foaming efficiency of these co‐polymers tended to increase with an increase in the hydrophilic character of the co‐polymer chains. The synthesized tri‐block co‐polymers, which can be used as anti‐foaming agents in paper‐coating applications of poly(vinyl acetate‐co‐butyl acrylate) latexes, showed low surface tension values, fast liquid drainage and efficient foam destruction. PEG 200‐b‐PDMS‐b‐PEG 200 was determined to be the most efficient anti‐foaming agent among all co‐polymers synthesized. |
