Title:
METHOD FOR PRODUCING POLY-4-METHYL-1-PENTENE OF LOWER MOLECULAR WEIGHT
Document Type and Number:
WIPO Patent Application WO/2023/063298
Kind Code:
A1
Abstract:
In the production method of the present invention, poly-4-methyl-1-pentene and another polyolefin are mixed and melt stirred at a temperature at or above the melting points of the two, making it possible to produce poly-4-methyl-1-pentene of lower molecular weight easily and safely.
