Glycerol derivatives of general formula (I) ##STR1## in which R=allyl, methylallyl, acryloyl or methacryloyl, R.sub.1 =R.sub.2 =glyoxyloyl, R.sub.1, R.sub.2 =H, glyoxyloyl; their preparation process, their use as cross-linking agnets and cross-linking or cross-linkable compositions containing them. These compounds are useful as crosslinking agents for woven and non-woven fibrous mats and textiles.

Glycerol derivatives, their preparation process, cross-linking

Glycerol derivatives of general formula (I)

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 C.sub.3 -C.sub.5 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 C.sub.1 -C.sub.12 alkanols; and 10 to 1% by weight of repeating units of general formula (I) ##STR1## where R=H or --CH.sub.3, R.sub.1 =H or C.sub.1 -C.sub.4 alkyl and R.sub.2 and R.sub.3 =C.sub.1 -C.sub.8 alkyl or a --CH.sub.2 --CR.sub.4 R.sub.5 --(CH.sub.2).sub.n --group in which n=0 or 1 and R.sub.4 and R.sub.5 =H or --CH.sub.3.
