Abstract
The properties of polypropylene differ depending on the way the polyme r is precipitated-either by slow cooling of its solution in m-xylene o r by fast mixing of the polymer solution with cold alcohol. The differ ences remain both in the polymer melt and in films prepared from the m elt. The difference in properties is caused by the different level of topological disorder in the polymer chains.
