Document Type and Number:
Japanese Patent JP4593938
Kind Code:
B2
Abstract:
Aqueous polymer dispersions used as binders for abrasive materials contain dispersed polymer with a glass transition point of -20 to +35[deg]C, obtained by radical emulsion polymerisation in presence of a polymer based on anhydride-forming unsaturated mono- and/or di-carboxylic acids, esters of such acids with hydroxy-amines, and optionally other monomers. The use of aqueous polymer dispersions (PD) as binders for the production of abrasive materials. Dispersions (PD) contain dispersed particles of polymer(s) (A1) with a glass transition point (Tg) of -20 to +35[deg]C, obtained by radical emulsion polymerisation in presence of a polymer (A2) which is derived from (a) 50-99.5 wt% unsaturated mono- and/or di-carboxylic acid(s) which can form anhydride groups, (b) 0.5-50 wt% unsaturated compound(s) selected from esters of unsaturated monocarboxylic acids and half-esters or diesters of unsaturated dicarboxylic acids with hydroxy-amine(s), and (c) up to 20 wt% other comonomer(s). Independent claims are also included for abrasive materials, abrasive paper, abrasive cloth and abrasive wool containing PD as binder.
