Polyolefin polymer having polar group, method for production thereof, and water dispersion material and mold release agent composition

Abstract

Disclosed are: a polyolefin polymer having a polar group represented by the general formula (i), which is produced by modifying, with a high degree of modification rate, a double bond in a polymer that has the double bond at one terminal, at both terminals, or in the inside of its polymer chain and is produced by a known method; a method for producing the polyolefin polymer; and a water dispersionmaterial and a mold release agent composition each comprising the polyolefin polymer. (i) wherein PO represents a polyolefin polymer produced by the polymerization of a monomer comprising an ethyleneor an olefin having 3 to 20 carbon atoms, wherein a group inside the parentheses represents a polar group; A and B independently represent any one selected from R1, a cyano group, C(O)OR1 and C(O)NR1R2, provided that A and B may together form a cyclic structure; M represents a metal cation or an onium cation; j represents the number of the metal cation(s) or the onium cation(s), and is an integerof 0 to 4; i represents the number of valency of the metal cation or the onium cation, and is an integer of 0 to 4; D and E independently represent any one selected from an oxygen atom, a nitrogen atom, a sulfur atom, R3, OR3, SR3 and NR3R4, provided that D and E may together form a cyclic structure; d and e represent the number of valency of the substituent D and the number of valency of the substituent E, respectively, and independently represent an integer of 0 to 4; R1, R2, R3 and R4 independently represent any one selected from a hydrogen, an optionally substituted alkyl, alkenyl, alkynyl, aralkyl or aryl group having 20 or less carbon atoms, and a group having a heterocyclic ring; and n represents the average number of the functional groups, and is a number of 0.80 to 10.0.

Description

technical field [0001] The present invention relates to a polyolefin polymer containing polar groups having more than one polar group at least any one of the single end, both ends and inside of the polymer, its production method, and its water dispersion Body and release agent composition. Background technique [0002] Low molecular weight polyethylene-based polymers belong to the class of polyethylene oligomers. The polyethylene oligomers are also called polyethylene waxes, and are broadly classified into animal and plant systems, mineral systems, petroleum refining systems, and synthetic systems. Examples of the polyethylene wax having a functional group at one end of the polymer chain include mineral-based montanic acid wax. However, since montanic acid wax is extracted and refined from natural lignite, there is a problem that the production cost is high. [0003] A system using a metallocene catalyst is exemplified as a synthesis system that can reduce the production ...

Problems solved by technology

[0006] However, the above-mentioned modification methods have problems such as low modification rate of double bonds to functional groups, homopolymerization of unsaturated carboxylic acid derivatives used, and labor-intensive purification.
