Laminates of sheet material and polyurethane foam

Loose fibre material e.g. viscose flock, may be bound to polyurethane foam by means of an adhesive acrylic ester polymer or co-polymer which is cross linkable and catalysed by acids. Preferred adhesives are obtained by co-polymerizing esters of acrylic or methacrylic acid with methylolated acrylamid...

Beschreibung
Zusammenfassung:	Loose fibre material e.g. viscose flock, may be bound to polyurethane foam by means of an adhesive acrylic ester polymer or co-polymer which is cross linkable and catalysed by acids. Preferred adhesives are obtained by co-polymerizing esters of acrylic or methacrylic acid with methylolated acrylamide or methacrylamide or their ethers with or without the ethylenically unsaturated monomers styrene, acrylic acid, acrylamide, acrylonitrile, maleic acid, vinyl chloride, vinylidene chloride and butadiene.
