Title:
HYDROPHILIC OIL REPELLENT POLYMER
Document Type and Number:
WIPO Patent Application WO/2024/043326
Kind Code:
A1
Abstract:
Provided is a hydrophilic oil repellent polymer having excellent shape transferability during molding that exhibits a high antifouling property in humid environments due to having high oil repellency in water. The polymer comprises: a structural unit A derived from ethylene and/or propylene; a structural unit B of formula (1); and a structural unit C of formula (2). In formula (1), L16 represents -(CH2)n-(Rf2O)p-(Rf3)h-(Si(Rf4)2O)g-Si(Rf1)3, Rf1 represents a hydrogen atom or a C1-15 alkyl group, Rf2 and Rf3 represent a C1-15 alkylene group, Rf4 represents a hydrogen atom or a substituted or unsubstituted C1-15 alkyl group or a substituted or unsubstituted C6-20 aryl group, n represents an integer of 0-10, p represents an integer of 0-15, h represents an integer of 0-15, and g represents an integer of 1-1000. In formula (2), L26 represents -(CH2)m-(Rr2O)q-Rr1, Rr1 represents a hydrogen atom or a C1-15 alkyl group or a C1-20 aryl group, Rr2 represents a C1-15 alkylene group, q represents an integer of 1-1,000,000, and m represents an integer of 0-10.
