Oxyalkylated adducts as multifunctional ingredients for rubber

摘要

Oxyalkylated adducts with linear or branched molecules, with short hydrophobic segments, with terminal groups of a different chemical nature, and with different lengths and nature of the chain were investigated as multifunctional agents for rubber. Results showed that there is an optimal length of the chain at which the activating, dispersing and plasticizing effects are maximal. The replacement of the one terminal hydroxyl group of the polyethylene glycols by a methoxyl group leads to an increase in the efficiency of monomethoxy PEG.
