Process for the preparation of telechelic 1,3-diene oligomers by controlled free radical polymerization of 1,3-dienes in the presence of stable free radicals

摘要

The present invention relates to the use of telechelic 1,3-diene oligomers comprising at least one 1,3-diene radical polymerization reaction in the presence of a stable nitroxide radical using a heat sensitive initiator such as hydrogen peroxide in aqueous solution And a manufacturing method thereof.;The present invention also relates to novel products as telechelic 1,3-diene oligomers as described above and their use for the preparation of di-or multiblock copolymers.
