Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="mame201300193-sec-0001" sec-type="section"> <p>Two novel benzonorbornadiene derivatives (OAc)₂BenzoNBD and (OCH₂PhBr)₂BenzoNBD monomers are synthesized and applied to copolymerize with 2‐butoxymethylene norbornene (BN) by the catalytic system of three‐dimensional geometry bimetallic nickel complex/B(C₆F₅)₃. The (OCH₂PhBr)₂BenzoNBD or (OAc)₂BenzoNBD content in the copolymers can be controlled 9.1–26.7% or 9.7–30.4% by varying the comonomer feed ratios (OCH₂PhBr)₂BenzoNBD or (OAc)₂BenzoNBD from 10 to 50%, respectively. Both of the poly(BN‐<italic>co</italic>‐(OCH₂PhBr)₂BenzoNBD)s and poly(BN‐<italic>co</italic>‐(OAc)₂BenzoNBD)s exhibit high thermal stability and high glass transition temperature, as well as excellent optical transparency. Copolymers are processed into films and fibers by solution casting method and electrospinning, respectively. The films show good transparency in the visible region while the fibers are uniform with smooth surface and diameters ranging from 700 to 1 200 nm.<inline-graphic xlink:href="ark:/27927/pgg55mvwsfw" content-type="mame201300193-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
