Chloropolyethylene, process for the manufacture thereof and its use

摘要

The invention provides finely dispersed, agglomeration-free chloropolyethylene having good rubber and anti-blocking properties. The invention provides furthermore a process for the manufacture of such a chloropolyethylene, according to which chlorination of the starting polyethylene is carried out in the presence of a dispersing agent system of poly-N-vinylprrolidone and hydrophobic silicic acid. This process allows also the use of polyethylene types having a pronounced tendency to agglomeration.
