Free radical polymerisation with matched initiator and chain transfer
agent has been used to produce carboxyl-terminated poly(2-ethylhexyl
acrylate) homopolymers of controlled molar mass. These polymers
were monofunctional with respect to carboxyl groups. The carboxyl
terminated polymers were converted to methacrylate macromonomers
via one of two methods. The first route used an acyl chloride
intermediate. The second involved an epoxide ring opening reaction.
The acyl chloride method gave macromonomers with high functionality
(>0.9), whilst the epoxide method gave typical functionalities of 0.5.
The macromonomers were characterised by Gel Permeation
Chromatography (GPC), Fourier Transform Infra-Red (FTIR) and
Proton Nuclear Magnetic Resonance (1 H NMR) spectroscopy. [Continues.]
