摘要:
A process for making a thermoplastic composition by dynamic cross-linking of a composition containing a thermoplastic matrix polymer A having functional groups reactive with epoxide groups and a polymer B having epoxide groups and secondary hydroxyl groups, and optionally other components. Separate addition of a cross-linking agent may be omitted.
摘要:
The invention relates to a thermal insulation material, and in particular an insulating material for a sub marine pipe, consisting of a composite comprising a thermoset elastomer and a filler or fillers comprising one or more hollow spaces such that the total volume of the hollow spaces occupies more than 10 vol. % of the volume of the composite, wherein the elastomer is cured in the presence of a peroxide and a co-agent.
摘要:
The invention relates to a method for devulcanizing a sulphur-cured rubber, which rubber contains a network of a polymer, which polymer has a main chain of carbon atoms, in which for the vulcanization per 40 carbon-carbon bonds in the main chain a maximum of 1 unsaturated carbon-carbon bond occurs, by heating the rubber in the presence of a devulcanizing agent. The devulcanizing agent is an amine compound.
