Polyether and its production method
First Claim
1. A polyether having a repeating unit of the following formula (1):
-
wherein R1 to R3 independently represent a hydrogen atom, a halogen atom, or a substituent, or two of R1 to R3 may be mutually bonded to form a ring;
R4 denotes hydrogen atom, an alkyl group with 1 to 10 carbons which may be substituted, a cycloalkyl group with 6 to 10 carbons which may be substituted, an aromatic ring with 6 to 14 carbons which may be substituted, a trialkylsilyl group which may be substituted, or a hydroxyalkyl; and
Ar represents a divalent aromatic group.

Abstract
The object of the present invention is to provide an organic polymer excellent in heat resistance and chemical resistance and having a low dielectric constant. This object can be achieved by a polyether resin having a repeating unit of following formula (1):
wherein R1 to R3 independently represent hydrogen atom, a halogen atom, or a substituent, or two of R1 to R3 may be mutually bonded to form a ring; R4 denotes hydrogen atom, an alkyl group with 1 to 10 carbons which may be substituted, a cycloalkyl group with 6 to 10 carbons which may be substituted, an aromatic ring with 6 to 14 carbons which may be substituted, a trialkylsilyl group which may be substituted, or a hydroxyalkyl; and Ar represents a divalent aromatic ring.
