Abstract
Improvements in the object of the main patent no. 237,977, by a process for producing flexible sheets or tapes, of predetermined flexibility, characterized in that they consist of solvent extraction of a polymerization product of 1-butene containing high polymer components, both isotactic as non-isotactic, with diethyl ether, methylene chloride, or pentane, and obtaining for that purpose a residue from which said non-isotactic high polymer components have been removed, and in the transformation of said residue into the desired article.
