Suspension polymerisation of methyl methacrylate: the use of polyelectrolyte stabilisers
thesis
posted on 2018-09-20, 13:48 authored by Stella GeorgiadouThe suspension polymerisation of methyl methacrylate (MMA), using polyelectrolyte
solutions, sodium polymethacrylate (PMA–Na) and ammonium polymethacrylate
(APMA) as suspending agents (stabilisers) was experimentally investigated in this
project. The topics examined were: the rheological behaviour of the aqueous
polyelectrolyte solutions; the factors that affect drop and particle sizes, dispersion and
stabilisation mechanism; and the factors that affect the critical conversion where the
onset of the gel effect occurs. The main advantage of using PMA–Na and APMA as
stabilisers for the suspension polymerisation is that these stabilisers are not grafted on
to the polymer beads' surface, and they are easily washed off and removed after the
polymerisation. [Continues.]
