摘要:
The present invention provides an air-conditioning system that supplies a gas to a space to be air-conditioned and/or discharges a gas from the space to be air-conditioned through a permeable membrane in order to provide an air-conditioning system that can sufficiently block suspended matter in the air such as SPM, and can sufficiently introduce outside air in which the permeable membrane is an asymmetric membrane formed of a polymeric material prepared by polymerizing a monomer composition containing a predetermined monomer.

摘要:
An asymmetric membrane contains a porous layer and a dense layer adjacent thereto. The porous layer and the dense layer are formed of a polymeric material. The porous layer and/or dense layer contains a filler. The amount of the filler is 11 parts by mass or more per 100 parts by mass of the polymeric material contained in the asymmetric membrane.

Provided is a siloxane compound having one end modified with at least one (meth)acrylic group via a spacer, the spacer being a straight chain having at least three ether bonds or a branched structure having at least one ether bond. The (meth)acrylic-modified siloxane compound is added to a heat or photo-curable composition, which cures into a product exhibiting water repellent, antifouling, lubricating and other properties inherent to siloxane.
