STUDY ON INTERPENETRATED POLYMER NETWORK COATING OF URUSHIOL-FERRIC POLYMER AND ALKYD RESIN

Interpenetrated polymer network (IPN) coating was prepared from urushiol-ferric polymer(PUF) and multihydroxyl alkyd resin (AlR). Its structure, mechanism of network formation and behavior of mechanical properties were characterized by DMTA, IR and other physico-chemical means. The solvent resistance and dynamic mechanical properties were also studied. The results showed that IPN was formed at definite ratio of PUF and AlR, with the combinated features of PUF coating and acrylic coating, especially its alkali resistance and solvent resistance were greatly improved.
