The invention relates to tetrachloroethyl esters of unsaturated organic acids of the general formula I ##STR1## where X stands for a substituent selected from the group consisting of COOH, CCOCH.sub.3, COOC.sub.2 H.sub.5, ##STR2## It further relates to their polymers and mixed polymers of the above monomers, namely with vinyl and diene compounds, and to methods for preparation both monomers and these polymers. To prepare the compounds of the general formula I, acyl chloride of the general formula II ##STR3## where Y stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##STR4## AND ##STR5## IS TREATED WITH CHLORAL, ADVANTAGEOUSLY IN THE PRESENCE OF A MINERAL ACID OR SALT, FOR EXAMPLE WITH ADDITION OF SULFURIC ACID AND FERRIC CHLORIDE, RESPECTIVELY.

Polymers of tetrachloroethyl esters of unsaturated organic acids, and

Method for producing polymers comprises connecting polymeric molecules at least one of which contains tertiary amino groups chemically bound in the chain in the presence of materials such as elemental halogens, compounds of the elements of groups 3 through 8 of the Periodic Table containing one or more halogen atoms or halogen containing organic compounds. It is possible to connect chains of identical or different types and in this way increase the molecular weight, produce block copolymers, cure films and varnishes and perform vulcanization and the like at ambient temperature.

Method for producing polymers

Process for producing polymers comprising connecting polymeric molecules which contain chemically bound tertiary amino groups in the chain by oxidizing the macromolecules to be connected with air or an oxidizing agent such as compounds containing a peroxidic bond, for example, inorganic and organic peroxides, or organic anhydrides. It is possible to connect chains of identical or different types and in this way increase the molecular weight, produce block copolymers, cure films of varnishes and perform vulcanization and the like at ambient temperature.

Process for producing of polymers by connecting of polymeric molecules

Homopolymers and mixed polymers of tetrachloroethoxyethyl esters, in particular of tetrachloroethoxyethyl acrylates and tetrachloroethoxyethyl methacrylates having the general formula ##STR1## WHEREIN X is a substituent selected from the group consisting of hydrogen and CH.sub.3 radical. Homopolymers and mixed polymers of tetrachloroethoxyethyl esters with vinyl and/or diene compounds. Method for preparation of these homopolymers and mixed polymers.

Homopolymers and copolymers of tetrachloroethoxyethyl esters and method

Monomeric conjugated or unconjugated organic compounds are polymerized in an initiator systems consisting of an organic peroxide and a macromolecular compound consisting of a polymer or copolymer of styrene or styrene derivative containing at least one tertiary amine group chemically bound by all its valences to carbon atoms in its macromolecule.

Process for the polymerization and copolymerization of vinyl and diene

Tetrachloroethoxyethyl acrylate and tetrachloroethoxyethyl methacrylate of the general formula ##STR1## are provided, where X is a hydrogen atom or CH.sub.3 radical. Also their homopolymers and mixed polymers are combined with vinyl and diene compounds. The aforesaid monomers are prepared by reacting the compound of the general formula ##STR2## with thionyl chloride, preferably in presence of compounds able to bind released hydrogen chloride, such as organic or inorganic bases, for instance, pyridine, triethylamine and sodium carbonate.

Tetrachloroethoxyethyl esters and method for their preparation

Monomeric conjugated or unconjugated organic compounds are polymerized in an initiator system consisting of an organic peroxide and a macromolecular compound containing at least one tertiary amine group chemically bound by all its valences to carbon atoms in a macromolecule, and a method of making same.

The invention relates to tetrachloroethyl esters of unsaturated organic acids of the general formula I ##EQU1## WHERE X stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##EQU2## It further relates to their polymers and mixed polymers of the above monomers, namely with vinyl and diene compounds, and to methods for preparation both monomers and these polymers. To prepare the compounds of the general formula I, acyl chloride of the general formula II ##EQU3## where Y stands for a substituent selected from the group consisting of COOH, COOCH.sub.3, COOC.sub.2 H.sub.5, ##EQU4## is treated with chloral, advantageously in the presence of a mineral acid or salt, for example with addition of sulfuric acid and ferric chloride, respectively.
