| 摘要 |
Surface chemistry modified latex, obtained by radical emulsion polymerisation of ethylenic monomer(s) or polymer(s) with residual unsaturation in presence of water soluble or dispersible mono-, di- or tri-block copolymer(s) with a reactive end group capable of forming a radical and selected from dithioester, thioether-thione, dithiocarbamate and xanthate groups. Independent claims are also included for: (a) redispersible powder obtained by drying the latex; (b) formulations containing latex or powder as above for use in building materials, painting, pressure sensitive adhesives and paper manufacture. |
