AQUEOUS DISPERSION OF THERMOCURABLE POLYMERS BASED ON ALKYL(METH)ACRYLATES, THEIR PROCESS OF PREPARATION AND THEIR USE AS BINDERS AND/OR IMPREGNATING AGENTS

摘要

These aqueous dispersions contain a copolymerizate containing 90 to 99% by weight of repeating units resulting from the polymerization of a mixture of monomers (a) based on 0.1 to 10% by weight of alpha,beta-ethylenic mono- and/or di-carboxylic C3-C5 acid and/or their amides, 0 to 10% by weight of styrene and/or acrylonitrile, the remainder of the esters of (meth)acrylic acid with C1-C12 alkanols; and 10 to 1% by weight of repeating units of general formula (I) (I) where R=H or -CH3, R1=H or C1-C4 alkyl and R2 and R3=C1-C8 alkyl or a -CH2-CR4R5-(CH2)n-group in which n=0 or 1 and R4 and R5=H or -CH3.
