Title:
COMPOSITE MOLECULARLY ORIENTED FILM
Document Type and Number:
Japanese Patent JPH04345627
Kind Code:
A
Abstract:
PURPOSE:To obtain a composite molecularly oriented film which can give an ion-selective electrode which can measure stably in high sensitivity chloride ions in a biological fluid by forming a film comprising a specified linear polymer and a polyether compound or a cyclic polyether compound. CONSTITUTION:A composite molecularly oriented film comprising a linear polymer (A) containing at least 50wt.% units represented by formula I and a cyclic polyether compound represented by formula II or a cyclic polyether compound (B) represented by formula III. In the formulas, X is a nonionic group having one or two long-chain hydrophobic groups or one linear hydrophobic group containing a rigid part in the chain; Y is a group selected from among those of formulas IV and V, etc., (wherein R<3> is H or methyl; R<2> is a bivalent group selected from among -CO-, -COO-, -O- and -CONH-; n is 1-4; m is 1 or 2; R<1> is H, methyl, cyano or halogen; j is 1 or 2; R<4> is H or methyl; and R is 10-22C linear alkyl.
