Resumen:
Several studies have recently reported the use of monofunctional octahedral oligomeric silsesquioxanes
(monofunctional POSS) to modify polymer networks. In most of these studies the final material is depicted
as a network with pendent POSS units randomly dispersed in the structure. The aim of this paper is to show that
this representation is generally not correct due to the occurrence of a polymerization-induced phase separation
(PIPS) process. In this sense, monofunctional POSS are not different from different types of rubbers, thermoplastics,
or liquid crystals used to modify polymer networks. Although some authors have noticed the occurrence of PIPS
in particular systems, a comparative study of the effect of the chemical structure of POSS and its prereaction
with one of the monomers on the morphologies generated has not been previously reported. Glycidyloxypropylheptaisobutyl
POSS (iBu-GlyPOSS) and glycidyloxypropyl-heptaphenyl POSS (Ph-GlyPOSS) were used to modify
an epoxy network based on diglycidyl ether of bisphenol A (DGEBA) and 4,4¢-methylenebis(2,6-diethylaniline)
(MDEA). POSS was introduced in the formulation either nonreacted or prereacted with MDEA (molar ratio
POSS/MDEA: 1/10). While both nonreacted and prereacted iBu-GlyPOSS were soluble in the epoxy-amine
precursors at the polymerization temperature (135 °C), only prereacted Ph-GlyPOSS could be dissolved in epoxyamine
precursors. For every case a polymerization-induced phase separation took place. For the nonreacted iBu-
GlyPOSS this process led to a dispersion of spherical particles with sizes in the range of the micrometers that
crystallized upon cooling. Both prereacted POSS led to different types of amorphous biphasic structures. Therefore,
the nature of the organic inert group and the prereaction of a monofunctional POSS can be used to control the
morphologies generated in the POSS-modified polymer network.
