POLYOLEFIN COPOLYMER, AQUEOUS DISPERSION USING SAID POLYOLEFIN COPOLYMER AND MANUFACTURING METHOD THEREFOR, AND LAMINATE USING SAID POLYOLEFIN COPOLYMER

摘要

Disclosed is a polyolefin copolymer comprising an olefin hydrocarbon unit and an N-substituted imide unit derived from an unsaturated carboxylic acid anhydride unit, the polyolefin copolymer being characterized in that : the content of the N-substituted imide unit derived from an unsaturated carboxylic acid anhydride unit is 0.1 mol% or more and less than 10 mol%; and the N-substituent of the N-substituted imide unit derived from an unsaturated carboxylic acid anhydride unit is a substituent represented by the following formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ- (CH 2 ) n NR 1 R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein R 1 and R 2 each represent an alkyl group having 1 to 5 carbon atoms or a hydroxyalkyl group having 1 to 5 carbon atoms, and n represents an integer of 1 to 5.
