Abstract
A water and oil repellent composition containing, as an effective component, a copolymer comprising the following polymeric units (a), (b) and at least one member selected from (c) and (d): polymeric units (a): Polymeric units of a (meth)acrylate having a polyfluoroalkyl group; Polymeric units (b): Polymeric units of 2-isocyanate ethyl (meth)acrylate with the isocyanate group blocked; Polymeric units (c): Polymeric units of vinyl chloride; and Polymeric units (d): Polymeric units of an alkyl (meth)acrylate.
Claims17
A water and oil repellent composition containing, as an effective component, a copolymer comprising the following polymeric units (a), (b), and at least one member selected from (c) and (d):
- polymeric units (a) of a (meth)acrylate having a polyfluoroalkyl group;
- polymeric units (b) of 2-isocyanate ethyl (meth)acrylate with the isocyanate group blocked;
- polymeric units (c) of vinyl chloride;
- and
- polymeric units (d) of an alkyl (meth)acrylate
- with the proviso that said copolymer does not contain a polymeric unit of a (meth)acrylate having a polyoxyalkylene chain.
A method for producing a water and oil repellant composition, which comprises copolymerizing a polymerizable monomer mixture comprising a (meth)acrylate having a polyfluoroalkyl group, 2-isocyanate ethyl (meth)acrylate with the isocyanate group blocked and at least one member selected from vinyl chloride and an alkyl (meth)acrylate, in the presence of a medium, with the proviso that said polymerizable monomer mixture does not contain a (meth)acrylate having a polyoxyalkylene group.
