Abstract:
The invention relates to a method for radical polymerization of one or several ethylenically unsaturated compounds, characterized in that it consists in providing at least 80.8 percent by weight ethylenically unsaturated compounds in relation to the total weight of the ethylenically unsaturated compounds, adding at least one polymerization initiator for radical polymerization in at least two steps, wherein more polymerization initiator is added in the second step than in the first.
