Abstract
The present invention provides a thermosetting polyether resin obtained by polycondensing a dihalogen compound with a bisphenol compound to obtain a polyether resin having a repeating unit represented by the formula (1), and introducing a functional group which causes a cross-linking reaction by heating into the resulted polyether resin; The present invention also provides a polyether resin having a low dielectric constant represented by the formula (3):
Claims8
A thermosetting polyether resin obtained by polycondensing a dihalogen compound with a bisphenol compound to obtain a polyether resin having a repeating unit represented by the formula (1), and introducing a functional group which causes a cross-linking reaction by heating into the resulted polyether resin;
- wherein each of R1 to R8 is independently selected from the group consisting of hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, an alkyl group having 1 to 10 carbon atoms which may be substituted, a cycloalkyl group having 4 to 10 carbon atoms which may be substituted, a OR9 group, and a phenyl group which may be substituted;
- R9 is selected from the group consisting of hydrogen atom, an alkyl group having 1 to 10 carbon atoms which may be substituted, a cycloalkyl group having 4 to 10 carbon atoms which may be substituted, and a phenyl group which may be substituted;
- X is selected from any one or more groups described below;
- Y is selected from a single bond, a hydrocarbon group having 1 to 20 carbon atoms, or any one or more of —O—, —CO— and —SO2—;
- each of Q1 to Q12 is independently selected from the group consisting of an alkyl group having 1 to 10 carbon atoms which may be substituted, a cycloalkyl group having 4 to 10 carbon atoms which may be substituted, and a phenyl group which may be substituted;
- m represents an integer from 0 to 4;
- n represents an integer from 0 to 3;
- Z is selected from the group consisting of hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, a —OZ1 group, and a —N(Z2)(Z3) group;
- each of Z1 to Z3 independently selected from the group consisting of hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, an alkynyl group having 2 to 10 carbon atoms, and a group carrying an ether group having 1 to 10 carbon atoms.
