Vm. Mikhalchuk et al., EFFECT OF REACTION CONDITIONS ON THE STRUCTURE OF INTERPENETRATING POLYMER NETWORKS - V - THE INFLUENCE OF A HIGH-ENERGY SURFACE ON CURING OF EPOXY-ALLYLIC INTERPENETRATING NETWORKS, Polymer networks & blends, 7(4), 1997, pp. 133-137
By the methods of absorption IR-spectroscopy, IR-spectroscopy of total
attenuated inner reflectance, TAIR, and pulsing NMR-spectroscopy, the
effect of a high energy surface on the formation of epoxy-allylic int
erpenetrating polymer networks had been investigated. By polymerizatio
n of epoxy oligomer at the interface with solid and by formation of si
multaneous IPN, where the second component is diallylic monomer, the s
olid effect manifests itself in total retardation of the conversion of
reaction able groups. At the initial stages of the IPN formation, the
re is observed selective adsorption of epoxy oligomer at the interface
. This effect leads to the diminishing the rate of opening of epoxy gr
oups and to decreasing their conversion at the latest stages of curing
.
