MODIFIED OPEN-CELL FOAMS AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a method for producing modified open-cell foams consisting in bringing into contact (a) open-cell foams whose density ranges from 5 to 500 kg/m³ and average pore diameter ranges from 1µm to 1mm with (b) an aqueous formulation of at least one type of compound containing at least one half-aminal or aminal group per molecule or at least one type of polymer, in which at least one type of comonomer containing an OH or ß-dicarbonyl or epoxy group is incorporated by polymerisation.
