| Abstract: | Through the ways of physical blend and core shell latex polymerization of chemical blend,and forming chemical bond between PU chain and PA chain,water borne polyurethane modified with acrylic resin were studied.IR spectrum analysis with water borne polyurethane modified acrylic resin indicated that hydrogen bond existed in water borne polyurethane modified with acrylic resin here;compatbility and degree of mixing in PUA or PU/PA materials system were developed by formation of chemical bond in the chain between PU and PA;micro phase separation was formed by carrying core shell latex polymerization;and compatibility and degree of mixing between hard segment of PU chain and PA chain were especially improved in PU/PA blend. |
