Abstract:
A method of manufacturing modified epoxysiloxanes comprising the steps of:a) implementation of a condensation of an epoxyalkoxysilane of the general structure 1 with a silanol of the general structure 2 ##STR2##to produce an alkoxy-group-containing epoxysiloxane condensate, whereby R.sup.1 is selected from the group consisting of an alkyl with 1 to 22 C atoms and an aryl, R.sup.2 is selected from the group consisting of glycidyloxyalkyl, epoxyalkyl and an epoxycycloalkyl, R.sup.3 is selected from the group consisting of OR.sup.1, R.sup.2, an allyl and an aryl, R.sup.4 is selected from the group consisting of an alkyl and an aryl, R.sup.5 is selected from the group consisting of OHl and R.sup.4, and n is a whole number greater than 1; andb) carrying out a condensation of the alkoxy-group-containing epoxysiloxane condensate produced in step (a) with a stoichiometric quantity of an organic compound comprising a carbon structure having 1 to 24 C atoms and at least one condensable functional group.
