摘要

Over 2×10*8 tons of polymers are produced every year

and a large portion of polymers faces the degradationproblem. There are many effective methods to protect polymers against degradation and the addition of stabilizers to polymerremains the most convenient and effective way of enhancing polymer life and performance. In this article

a series of effectivestabilizers with optimal molecular weight (MW)

including common

monomeric and polymeric stabilizers (antioxidant andlight stabilizer) were synthesized using isocyanation

controlled isocyanation

hydrosilylation

epoxide addition

macroreaction of stabilizing functional compounds and polymerization stabilizers.The structure and performance of these new stabilizers were characterized by using IR

NMR

UV-spectra

XPS and elemental analysis.The current development of stabilizer synthesis was also reviewed.
