Abstract

PURPOSE: To obtain title foam, which is highly air-permeable and suitable for an air-conditioner filter, oil filter, filter for purification of water, etc., by use of a specified polyol mixture together with an organic carboxylic acid (anhydride).
CONSTITUTION: 100pts.wt. of mixed polyols, composed of (a) a poly(oxypropylene- oxyethylene)polyetherpolyol containing 51W98wt% ethylene oxide and (b) a poly (oxypropylene-oxyethylene)polyetherpolyol containing ≥51wt% propylene oxide, are reacted with a polycyanate, with addition of 0.1W10pts.wt. of an organic carboxylic acid (anhydride) and, if necessary, 0.05W5pts.wt. of urea, by means of one-shot process, to obtain purpose product.
EFFECT: A hydrophilic foam, of good foam stability, is obtained.
USE: Clothing, bed for cultivation of plants.
