Abstract: THESE ARE DISCLOSED ELASTIC MANUFATUCRED ARTICLES, INCLUDING ELASTIC FIBERS AND IFLMS BASED ON UNSATURATED, VULCANIZABLE COPLYMERS OF ETHYLENE, AT LEAST ONE BRANCHED ALPHA-OLEFIN, HYDROCARBON MONOMERS CONTAINNG AT LEAST TWO DOUBLE BONDS AND, OPTINALLY, PROPYLENE, WHICH COPOLYMERS ARE AMORPHOUS IN THE RELAXED STATE BUT CRYSTALLIZABLE BY STRETCHING. THE COPOLYMERS MUST CONTAIN, BY MOLES, 70-90% OF POLYMERIZED ETHYLENE, 1-29% OF POLYMERIZED BRANCHED ALPHA-OLEFIN, 0.05-3% OF THE POLYMERIZED HYDROCARBON MONOMER CONTAINING AT LEAST TWO DOUBLE BONDS, AND 0-28% OF POLYMERIZED PROPYLENE. METHODS FOR OBTAINING THE COPOLYMERS USING CATALYSTS BASED ON VANADIUM COMPOUNDS AND METALLORGANIC ALUMINUM COMPOUNDS, AND FOR EFFECTIVELY CROSS-LINKING THE COPOLYMERS ARE ALSO DISCLOSED.

Abstract: Copolymers including diallyldialkylammonium compounds of the formula:

WHEREIN R1 and R2 are independently selected from the group consisting of lower alkyl, halogen substituted lower alkyl and phenyl and X is OH, a halogen or an inorganic or organic anion, alkenyl monomers, such as methyl vinyl ketone and halogen containing vinyl monomers, are useful in the preparation of anion permoselective membranes.

Abstract: THERE ARE DISCLOSED UNSATURATED TERPOLYMERS OF ETHYLENE, PROPYLENE, AND HYDROCARBON MONOMERS CONTAINING AT LEAST TWO DOUBLE BONDS, WHICH TERPOLYMERS EXHIBIT FROM 20% TO 75% CRYSTALLINITY BUT ARE VULCANIZABLE TO ELASTOMERIC MATERIALS. THE TERPOLYMERS ARE OBTAINED BY POLYMERIZING A MIXTURE OF ETHYLENE, PROPYLENE AND AT LEAST ONE OF THE HYDROCARBON MONOMERS CONTAINING AT LEAST TWO DOUBLE BONDS IN CONTACT WITH A CATALYST PREPARED FROM TITANIUM OR VANADIUM COMPOUNDS AND AN ORGANOMETALLIC ALUMINUM COMPOUND.

Abstract: THERE ARE DISCLOSED CROSSLINKED TERPOLYMERS OBTAINED FROM HIGH MOLECULAR WEIGHT, NORMALLY SOLID, ESSENTILLY LINEAR, ADDITION TERPOLYMERS OF ETHYLENE, PROPYLENE AND ALKENYLSILANES, SELECTED FROM THE GROUP CONSISTING OF VINYLSILANE, ALLYLSILANE, PROPENYLSILANE, BUTENYLSILANE, DIMETHYLALLYLSILANE, BUTENYLALLYL SILANE, CRYLOCHEXYLALLYLSILANE, AND CYCLOHEXYLBUTENYLSILANE, WHICH TEROLYMERS CONTAIN, BY MOLS, FROM 65% TO 80% OF ETHYLENE, FROM 20% TO 35% OF PROPYLENE, AND FROM 0.02% TO 5.0% OF ALKENYLSILANE. THE CROSSLINKED TERPOLYMERS ARE CHARACTERIZED IN HAVING SI-O-SI CROSSLINKS BETWEEN SILICON ATOMS OF THE POLYMERIZED ALKENYLSILANE UNITS IN DIFFERENT MACROMOLECULAR CHAINS OF THE TERPOLYMERS, AS EVIDENCED BY EXAMINATION OF THE INFRA-RED SPECTRA THEREOF. A PROCESS FOR OBTAINING THE TERPOLYMERS WITH THE AID OF CATALYSTS PREPARED FROM TRANSITION METAL COMPOUNDS AND ORGANOMETALLIC COMPOUNDS OF ALUMINUM, AND A PROCESS FOR CROSSLINKING THE TERPOLYMERS IN A LIQUID NON-SOLVENT SWELLING AGENT FOR THE TERPOLYMERS ARE ALSO DISCLOSED.
