Abstract (en)

[origin: WO2020165740A1] The present invention relates to a cross-linkable functional latex, comprising: 10.0 to 5.0 wt% cross-linkable latex polymer based on styrene and or similar monomers in 90.0to 99.5 wt% comprising at least a carboxy functional group in an amount of at least 0.05 wt% with respect to the total weight of said latex; optionally up to 15.0 wt% cross-linker; up to 15.0 wt% of a surfactant; and 40.0 to 70.0 wt% aluminium trihydroxide; supplemented with water up to 100.0 wt%, whereby the cross-linkable functional latexcomprises a functional monomer, said functional monomer being a hydroxy-or a carboxy-functional monomer or a mixture thereof. In addition, the invention also relates to a method for producing a cured latex foam compound, a cured latex foam compound obtained by such method, an arrangement comprising said cured latex foam composition and the use of a cross-linkable functional latex according to the present invention for producing a cured latex foam composition.
