FIR BICONSTITUENT POLIOLEFINIC SI PROCEDEU DE OBTINERE A ACESTUIA

摘要

The process comprises drawing of material consisting of isotactic polypropylene 65-75 and n-dihexylmaleate copolymer 35-25 per cent. Spinning gives a total drawing rate of 1:2.90 - 1:2.95 with reduced material and energy consumption. The creep of the two constituents is 12-16 and 6.5-7.5 g/10 minutes.
