Abstract
1,001,912. Hydrophilic foam plastics. DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT. Jan. 31, 1964 [Feb. 1, 1963], No. 4314/64. Headings C3C and C3R. [Also in Division B2] Foam plastics consisting of synthetic water insoluble polymers containing -NH-CO- groups are treated with either a mixture of polymers of acrolein and/or substituted acrolein, with one or more polysaccharides which are soluble or capable of swelling in water; or a single polysaccharide in which 5 to 95% of the primary hydroxyl groups have been converted to aldehyde groups by oxidation; and then dried to give a hydrophilic foam plastic. The polymers of acrolein or α-substituted acrolein have mean molecular weights in the range 1000 to 500,000, contain reactive aldehyde groups and are present in a hydrophilizing mixture in amounts from 2 to 95% by weight, the remainder being polysaccharide. Specified polysaccharides are polyhexoses such as degraded cellulose including hemi-cellulose, lichenins, as well as etherified cellulose derivatives, starch and its macro-molecular degradation products, polyuronic acids such as esterified pectins, alginates, polypentoses such as arabans and xylans. The average molecular weight is in the range 1000 to 500,000. The mixture of the polysaccharide and the acrolein polymer is used as a 0À5 to 25% by weight aqueous solution. Dialdehyde starch is specified as a polysaccharide containing aldehyde group.
