摘要

Abstract

Novel copolymerization of ethylene with substituted allenes (CH

=C=CH—R

: R =

-butyl

: R =

-octyl) using bis(

-enaminoketonato)titanium catalysts [PhN=C(R

)CHC(R

)O]

TiCl

(

: R

= CF

= CH

;

: R

= Ph

= CF

) has been investigated. In the presence of modified methylaluminoxane

these catalysts can copolymerize ethylene with substituted allenes

affording copolymers with unimodal molecular weight distributions and homogeneous compositions. By varying the reaction conditions

the comonomer incorporation can be tuned in the range of 0-3.6 mol%.

H-NMR spectra reveal that the copolymerization proceeds through 1

2-insertion fashion of allene comonomer exclusively

and the regioselective nature maintains under various reaction conditions. The retained intra-chain double bond can be converted into the epoxy group under mild conditions.
