Title: ANTIFOGGING POLYOLEFIN GRAFT AND PREPARATION METHOD THEREFOR
Abstract:
Disclosed are an antifogging polyolefin graft and a preparation method therefor, prepared via a two-step grafting method, specifically comprising the following steps: 1) a polyolefin undergoes a grafting reaction with a peroxide initiator and a polar monomer to produce a polar monomer graft A; and 2) the polar monomer graft A is then further grafted with a hydrophilic macromolecule by the effect of a chemical bond to produce an antifogging polyolefin graft B. The antifogging polyolefin of the present application is characterized by great hydrophilic performance, is not prone to be washed away by rain, and provides lasting antifogging effects.
