Title:
異なる二種類の構造単位を有する芳香族ポリケトン
Document Type and Number:
Japanese Patent JP6879303
Kind Code:
B2
Abstract:
A polymer comprising a structural unit represented by the following general formula (I-1) and a structural unit represented by the following general formula (I-2). In general formulae (I-1) and (I-2), X and X' each independently represent a C6-50 divalent group including an aromatic ring; Y represents a C5-50 divalent group comprising both an alicyclic group and C1-10 alkylene groups which connect the alicyclic group and the carbon atoms contained in the carbonyl groups adjoining the Y; Y' represents a C3-50 divalent group comprising an alicyclic group directly bonded to the carbon atoms contained in the carbonyl groups adjoining the Y'; and m and n each represent an integer of 3-1,000.
