Abstract
Random incorporation of polar groups into polyolefins
via
coordination copolymerization has made a great progress in the past decades. In contrast
the preparation of polar functionalized conjugated diene rubbers receives less attention
although the polar groups play an important role in improving the mechanical properties of green tire. In this work
one kind of polar conjugated diene mononer IP-OTBS is prepared. Then
a series of rare-earth metal complexes
1‒5
which show different selectivities for isoprene polymerization
are utilized to initiate the homopolymerization of IP-OTBS in the presence of cocatalysts [Ph

and Al
i
Bu

. Among them
complexes
1
and
2
still show high
cis
-1
4 selectivity (
>
98%) for IP-OTBS polymerization and
in contrast
the maximum value of 3
4 selectivity is 82.2% achieved by complex
3
. Complexes
4
and
5
which show higher 3
4 selectivity (
>
98%) for isoprene polymerization
show moderate 3
4 selectivity (67.6%) and inert
respectively
under the same conditions. The copolymerizations of IP-OTBS with isoprene and butadiene using complex
2
generate the functional polybutadiene and polyisopene with
cis
-1
4 content of 10.2 mol% and 16.7 mol%
respectively. The bulky tert-butyldimethylsilane masked polybutadienes are readily transformed into the hydroxyl group functionalized polybutadienes or polyisoprene
via
the reaction with Bu
4
NF. Finally
we demonstrate that the p
olar group functionalized conjugated diene rubbers could be obtained
via
the stereoselective (co)polymerization of IP-OTBS by using rare-earth metal catalysts.
