New reactive surfactants (RS) and synergistic reactive surfactants (SRS), c
ontaining reactive groups and longer unsaturated apolar hydrocarbon chains
have been synthesised and applied in filled and flame-retarded polymer syst
ems, respectively. These additives are capable of reactions with the polyme
r matrix and the disperse phase as well. The reaction of these compounds wi
th polyolefins was proven on model system by surface analysis, while their
reaction with fillers was demonstrated by DSC. The interface modification i
n filled/reinforced polymer systems and polymer blends resulted in improved
mechanical properties. while in pigmented PE it contributed to higher phot
ostability. Furthermore, the efficiency of intumescent flame retardant addi
tives in polyolefins could be enhanced. (C) 2001 Elsevier Science B.V. All
