Abstract

A star-shaped macromolecular antioxidant (β-CD-DBHMP) was synthesized via a two-step method by binding 2,6-di-tert-butyl-4-hydroxy methyl phenol (DBHMP) onto per-2,3-acetyl-β-cyclodextrin (β-CD-core) using isophorone diisocyanate (IPDI) as linkage. FT-IR, 1 H –NMR, MALDI-TOF MS and GPC results confirmed the star-shaped structure of β-CD-DBHMP. Accelerated thermal aging test and water extraction test indicated β-CD-DBHMP could protect natural rubber (NR) against thermal oxidation and also exhibit good extraction resistance in NR matrix.
