Abstract

Partially polymerized hydrolysis products of beta-halogenethylsilanes, with a degree of polymerization of 3 maximum obtained by hydrolysis of beta-halogenethylsilanes of the formula ** (See formula) ** in which X stands for chlorine or bromine, A means a radical -S-R1, (see formula), -O-R4, phenyl, chlorine or lower alkyl such as methyl, B stands for a radical -S-R5, (see formula), -O-R6, phenyl, chlorine or lower alkyl such as methyl, C means a radical -S-R7, (see formula), (see formula), where n is an integer up to 5, in addition a radical -O-R8, phenyl, -OH, chloro or lower alkyl such as methyl, where again the radicals R1, R5 and R7 independently mean radicals of alkyl, which may be substituted by alkoxy, alkylthio, alkoxycarbonyl, phenyl, cycloalkyl or heterocyclic radicals, as well as alkenyl, alkynyl, cycloalkyl and cycloalkenyl radicals, in addition to phenyl radicals optionally substituted one or more times by alkyl, alkoxy, alkylthio and/or halogen, benzyl radicals optionally substituted one or more times by alkyl, alkoxy, alkylthio and/or halogen, R3 represents alkyl, which may be substituted by alkoxy, alkylthio, phenyl, cycloalkyl or by a heterocyclic radical, in addition cycloalkyl, cycloalkenyl, alkenyl, alkynyl, phenyl, optionally substituted one or more times by alkyl, alkoxy, alkylthio and/or halogen, benzyl substituted one or more times optionally by alkyl, alkoxy, alkylthio and/or halogen, R2 means hydrogen or the same as R3, where, however, also R2 and R3 can together with the neighboring nitrogen atom form a saturated or unsaturated ring system, R4, R6 and R8 signify, independently of one another, alkyl radicals, alkyl radicals substituted by halogen, alkoxy, alkenyloxy, phenoxy, cycloalkyl, alkylthio, alkoxycarbonyl, by means of a heterocyclic radical and/or by di-alkylammonium and tri-alkylammonium, alkenyl, cycloalkenyl, phenyl radicals substituted one or more times by phenyl or alkenyl substituted by halogen, alkynyl, cycloalkyl, optionally by cyano, nitro, alkyl, halogenalkyl, alkoxy, alkythio, alkanoyl and/or alkoxycarbonyl, optionally substituted benzyl radicals or several times by alkyl, alkoxy and/or halogen or the group -CO-R9, where R9 represents an alkyl, alkenyl or alkynyl radical, a halogenoalkyl or halogenoalkenyl radical an alkyl or alkenyl radical substituted by alkoxy, alkylthio, cycloalkyl or phenyl, where the phenyl can be substituted by alkyl, alkoxy and/or halogen, in addition represents an alkoxyalkyl, alkoxycarbonylalkyl, benzoylalkyl or phenyl radical, the latter being optionally substituted by halogen, lower alkyl or or alkoxy and finally represents a pentagonal or hexagonal heterocyclic radical, in addition R4, R6 or R8, also in the meaning of -COR9, together with neighboring atoms, can also form a saturated or unsaturated heterocyclic ring system containing silicon.
