Abstract

Two kinds of fluorinated polymers were synthesized: an acrylate polymer having a fluorinated triethylene glycol as a pendant group (2a) and a fluoroalkyl acrylate polymer (2b). The contact angle of these fluorinated polymers against water, non-fluorinated alcohols and fluorinated alcohols were evaluated. As compared with the fluoroalkyl polymer (2b), fluoroethylene glycol polymer (2a) showed smaller contact angle against water and non-fluorinated alcohols. This supports the proposition that changing the alkyl chain into the ethylene glycol-type chain gave some interaction between etheric oxygen and water or non-fluorinated alcohols. In addition, fluoroalkyl acrylate polymer (2b) showed remarkably low values of critical surface tension.

摘要

合成了两种含氟聚合物

一种是具有氟化三甘醇作为侧基的丙烯酸酯聚合物（2a）和一种丙烯酸氟烷基酯聚合物（2b）。评估了这些含氟聚合物对水、非氟化醇和氟化醇的接触角。与氟烷基聚合物（2b）相比，氟代乙二醇聚合物（2a）对水和非氟化醇的接触角较小。这支持了将烷基链变为乙二醇型链会使醚氧与水或非氟化醇之间产生某种相互作用的观点。此外，丙烯酸氟烷基酯聚合物（2b）的临界表面张力值极低。
