Resin, resin composition, and method for producing nonwoven fabric, textile product, separator, secondary battery, and electric double layer capacitor and nonwoven fabric using them

摘要

This invention makes it a subject to provide resin which can manufacture the heat resistant nonwoven fabric of a fine fiber diameter by the field spinning method, and has a structure represented by at least one chosen from the group which consists of following General formula (1)-(3). It is set as the resin which has at least 1 sort (s) chosen from the C10 or more alkyl group and the C4 or more fluoroalkyl group at the terminal of a principal chain. (In General Formula (1), each X independently represents a single bond or -NR ^3- . R ¹ and R ² each independently represent a divalent organic group having 4 to 30 carbon atoms. R ³ is And a hydrogen atom or a monovalent organic group having 1 to 10 carbon atoms, in General Formula (2), R ⁴ represents a divalent organic group having 4 to 30 carbon atoms, and R ⁵ represents a tetravalent organic group having 4 to 30 carbon atoms. In General Formula (3), R ⁶ represents a divalent organic group having 4 to 30 carbon atoms, R ⁷ represents a trivalent organic group having 4 to 30 carbon atoms, and l, m and n each represent an integer of 0 or more. However, l + m + n is 10 or more, and the structures represented by the general formulas (1) to (3) do not necessarily have to exist in succession, respectively.)
