Abstract
A polymer and a treating agent (such as a surface-treating agent) are provided that have excellent characteristics in such properties as water repellency, oil repellency, antifouling property and charge controlling property. The polymer contains a structural unit derived from fluorosilsesquioxane having an addition polymerizable group, or contains a structural unit derived from fluorosilsesquioxane having an addition polymerizable group and a structural unit derived from organopolysiloxane having an addition polymerizable group. The treating agent contains the polymer. An article treated with the treating agent is also provided.
Claims23
A polymer comprising a constitutional unit 1 represented by the formula (1):
- wherein
- Rf1 to Rf7 each independently represent fluoroalkyl having from 1 to 20 carbon atoms, in which arbitrary methylene may be replaced by oxygen, fluoroaryl having from 6 to 20 carbon atoms, in which at least one hydrogen is replaced by fluorine or trifluoromethyl, or fluoroarylalkyl having from 7 to 20 carbon atoms, in which at least one hydrogen in an aryl moiety is replaced by fluorine or trifluoromethyl;
- and
- L1 represents —Y1—O—CO— (wherein Y1 represents alkylene having from 2 to 10 carbon atoms bonded to Si), and R10 represents hydrogen, alkyl having from 1 to 5 carbon atoms or aryl having from 6 to 10 carbon atoms;
- or
- L1 represents —Y2-Ph- (wherein Y2 represents a single bond or alkylene having from 1 to 10 carbon atoms bonded to Si), and R10 represents hydrogen.
A method for producing a polymer, the method comprising:
- polymerizing a mixture comprising at least a monomer 1M represented by the formula (1M):
- wherein
- Rf1 to Rf7 each independently represent fluoroalkyl having from 1 to 20 carbon atoms, in which arbitrary methylene may be replaced by oxygen, fluoroaryl having from 6 to 20 carbon atoms, in which at least one hydrogen is replaced by fluorine or trifluoromethyl, or fluoroarylalkyl having from 7 to 20 carbon atoms, in which at least one hydrogen in an aryl moiety is replaced by fluorine or trifluoromethyl;
- and
- A1 represents an addition polymerizable reactive group.
