Abstract

Предлагается способ модифицирования альфа-олефиновых (со)полимеров для образования разветвленности. Более конкретно, изобретение относится к способу разветвления альфа-олефинов путем контактирования указанных альфа-олефинов с перекисным соединением, содержащим активированную ненасыщенную группу, при температуре выше 120С. Способ можно осуществить в атмосфере азота или при расплавленной форме в кислородсодержащей атмосфере.
