Abstract
|
A novel miktofunctional initiator (<B>1</B>), 2-hydroxyethyl 3-[(2-bromopropanoyl)oxy]-2-{[(2-bromopropanoyl)oxy]methyl}-2-methyl-propanoate, possessing one initiating site for ring-opening polymerization (ROP) and two initiating sites for atom transfer radical polymerization (ATRP), was synthesized in a three-step reaction sequence. This initiator was first used in the ROP of <IMGSRC="/giflibrary/12/epsi.gif"BORDER="0">-caprolactone, and this led to a corresponding polymer with secondary bromide end groups. The obtained poly(<IMGSRC="/giflibrary/12/epsi.gif"BORDER="0">-caprolactone) (PCL) was then used as a macroinitiator for the ATRP of <I>tert</I>-butyl acrylate or methyl methacrylate, and this resulted in AB<SUB>2</SUB>-type PCL-[poly(<I>tert</I>-butyl acrylate)]<SUB>2</SUB> or PCL-[poly(methyl methacrylate)]<SUB>2</SUB> miktoarm star polymers with controlled molecular weights and low polydispersities (weight-average molecular weight/number-average molecular weight < 1.23) via the ROP-ATRP sequence. © 2004 Wiley Periodicals, Inc.
