Abstract
A functional polymer membrane having a pore volume fraction of 0.6% or more and 3.0% or less by allowing a reaction of curing a composition containing a polymerizable compound (A) and a copolymerizable monomer (B).
Claims20
A functional polymer membrane having a pore volume fraction of 0.6% or more and 3.0% or less prepared by allowing a reaction of curing a composition containing a polymerizable compound (A) and a copolymerizable monomer (B),
- wherein the polymerizable compound (A) has at least two ethylenically unsaturated groups in its molecule, and is water soluble, and
- wherein a solid content of the polymerizable compound (A) is 20 to 85 parts by mass based on 100 parts by mass of the total solid content in the composition.
A method of producing a functional polymer membrane, comprising the step of:
- allowing a reaction of curing a composition containing a polymerizable compound (A) and a copolymerizable monomer (B), thereby adjusting a pore volume fraction to 0.6% or more and 3.0% or less,
- wherein the polymerizable compound (A) has at least two ethylenically unsaturated groups in its molecule, and is water soluble, and
- wherein a solid content of the polymerizable compound (A) is 20 to 85 parts by mass based on 100 parts by mass of the total solid content in the composition.
