Document Type and Number:
Japanese Patent JPH11511202
Kind Code:
A
Abstract:
The invention features a method for preparing telechelic 1,3-diene oligomers that consists in effecting the free radical polymerization of at least one 1,3-diene with a heat sensitive polymerization initiator such as hydrogen peroxide in the presence of a stable nitroxide radical. The invention also features as new products the said telechelic 1,3-diene oligomers and their use for obtaining di- or multi-blocks.
