Abstract

A water- and oil-repellent composition including a copolymer having a repeating unit derived from a hydrophobic monomer having an ethylenically unsaturated double bond and a hydrocarbon group having from 3 to 40 carbon atoms, and a repeating unit that is derived from a cyclic vinylidene monomer, which is a compound represented by formula (wherein X represents an aliphatic group having from 1 to 10 carbon atoms; and Z represents at least one atom or group that is selected from a hydrogen atom, a hydrocarbon group having from 1 to 6 carbon atoms, and halogen atoms). Also disclosed is method for producing the water- and oil-repellent composition; as well as a textile product to which the copolymer in the water- and oil-repellent composition is attached.

First claim

What is claimed is:

1 . A water- and oil-repellent composition comprising a copolymer,
wherein the copolymer comprises: a repeating unit derived from a hydrophobic monomer comprising one ethylenically unsaturated double bond and a hydrocarbon group having 3 to 40 carbon atoms; and a repeating unit derived from a cyclic vinylidene monomer that is a compound represented by the formula:

wherein X is an aliphatic group having 1 to 10 carbon atoms, and Z is at least one selected from the group consisting of a hydrogen atom, a hydrocarbon group having 1 to 6 carbon atoms, and a halogen atom,
wherein the copolymer is a non-fluorine copolymer.

2 . The water- and oil-repellent composition according to claim 1 , wherein the copolymer has an ester bond in a skeleton of a main chain.

3 . The water- and oil-repellent composition according to claim 1 , wherein X is an alkylene group optionally having a substituent or an alkylene group optionally interrupted by ethereal oxygen.

4 . The water- and oil-repellent composition according to claim 1 , wherein the hydrophobic monomer is a compound represented by the formula:
CH 2 ═C(—R 12 )—C(═O)—Y 11 —(R 11 ) k
wherein R 11 is an aliphatic hydrocarbon group having 3 to 40 carbon atoms, R 12 is a hydrogen atom, a monovalent organic group or a halogen atom, Y 11 is a divalent to tetravalent group composed of at least one selected from a direct bond, a divalent to tetravalent hydrocarbon group having 1 carbon atom, —C 6 H 4 —, —O—, —C(═O)—, —S(═O) 2 — and —NR′—, where R′ is a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms, and k is 1 to 3.

5 . The water- and oil-repellent composition according to claim 1 , wherein the copolymer comprises 10 parts by mole or more and 60 parts by mole or less of the repeating unit derived from a hydrophobic monomer and 20 parts by mole or more and 90 parts by mole or less of the repeating unit derived from a cyclic vinylidene monomer based on 100 parts by mole in total of the repeating units.

6 . The water- and oil-repellent composition according to claim 1 , which is for a textile product.

7 . A method for producing a water- and oil-repellent composition comprising a copolymer having an ester bond in a main chain, comprising:
copolymerizing a hydrophobic monomer comprising one ethylenically unsaturated double bond and a hydrocarbon group having 3 to 40 carbon atoms, with a cyclic vinylidene monomer represented by the formula:

wherein X is an aliphatic group having 1 to 10 carbon atoms and Z is at least one selected from the group consisting of a hydrogen atom, a hydrocarbon group having 1 to 6 carbon atoms, and a halogen atom.

8 . The method according to claim 7 , wherein the copolymerization is radical copolymerization.

9 . A textile product to which the copolymer in the water- and oil-repellent composition according to claim 1 is attached.
