摘要： A process for high sulfur content copolymer preparation comprising reacting sulfur in solid form with at least one crosslinker selected from organic compounds containing at least a double or triple bond, in the presence of at least one catalyst selected from dithiocarbamates, mercaptobenzothiazoles, xanthates, thiophosphates, at a temperature ranging from 110°C to 180°C, preferably from 120°C to 150°C, for a time ranging from 20 minutes to 12 hours, preferably ranging from 30 minutes to 10 hours. Said high sulfur content copolymer, depending on the glass transition temperature (Tg), can be of elastomeric or thermoplastic type and can be advantageously used in different applications. In case of an elastomeric-type high sulfur content copolymer, said copolymer can be advantageously used in different applications such as, for example, thermal insulation, conveyor belts, transmission belts, flexible tubes, elastomeric tire compositions. In case of a thermoplastic-type high sulfur content copolymer, said copolymer can be advantageously used, as such or in a mixture with other (co)polymers (for example, styrene, divinylbenzene), in different applications such as, for example, packaging, electronics, household appliances, computer cases, CD cases, kitchen, laboratories, offices and medical items, in building and construction.
