Abstract

This paper reports the flexible synthesis of 2,4,6,8,10-pentamethylundecane (PMU) as well as a chromatographic method for the separation of its diastereoisomers. This strategy offers a unique opportunity to accede to three model compounds of polypropylene (PP) of different tacticities (i.e., isotactic, syndiotactic, and atactic PP).

Key words

model hydrocarbons - polyolefins - total synthesis - HPLC - NMR
