| Abstract: | Soapfree cationic emulsion copolymerization of styrene (St) and butyl acrylate (BA) in the presence of cationic comonomer N,Ndimethyl,Nbutyl,N(3methacrylamidino)propyl ammonium bromide (DBMPA) was carried out using 2,2azobis (isobutyramidine hydrochloride)(AIBA) as initiator The size (D w),number(Np),and the surface properties of latex particles were characterized by means of PCS particle size analysizer,ionicexchange conductimetric titration respectively The stability of latex and the property of film were characterized using surface tension analysizer and DSC respectively |
