Polymerisation of Ketones

There are a few reports dealing with the coordination polymerisation of acetone in the presence of organometallic catalysts. Such a situation results from long-term instability of acetone polymers [283]. The polymerisation of acetone with metal alkyls such as triethylaluminium as catalysts has been reported [284,285] to produce polymers containing acetalic units (Table 9.3), which was confirmed by IR spectroscopy. 

However, in order to obtain polymers that might be relatively stable, polymerisations were carried out in two-component comonomer systems such as acetone/aldehyde or acetone/epoxide. Acetone copolymers, obtained in the presence of organometallic catalysts in this way, exhibited high crystallinity [284],
