摘要： A method of dispersing a solid particulate material in an aqueous medium by addition to the aqueous medium of a dispersing agent wherein the solid particulate material is to be used as a filler or pigment in a sheet material which is required to come into contact with foodstuffs, wherein the dispersing agent is a composition comprising: (1) up to 0.25% by weight, based on the dry weight of the particulate solid material, of a water-soluble salt of a poly(acrylic acid) having a weight average molecular weight not greater than 20,000, and (2) from 0.02% to 1.5% by weight, based on the dry weight of the particulate solid material, of either(a) an anionic polyelectrolyte which comprises a water-soluble salt of a copolymer of acrylic acid with acrylamide; or(b) a water-soluble condensed phosphate salt.

摘要： PCT No. PCT/GB96/02268 Sec. 371 Date Jun. 1, 1998 Sec. 102(e) Date Jun. 1, 1998 PCT Filed Sep. 12, 1996 PCT Pub. No. WO97/10308 PCT Pub. Date Mar. 20, 1997There is disclosed a process for preparing a concentrated aqueous suspension of a finely ground particular material, which process comprises (a) preparing an aqueous suspension comprising at least 20% by weight of the particulate material comprising calcium carbonate in coarse particular form; (b) grinding the suspension formed in step (a) in the presence of a polycarboxylate dispersing agent for the particular material in a grinding process where the pH is not less than 10 to produce an aqueous suspension wherein at least 90% by weight of the particles or the particulate material have an e.s.d. less than 2 mu m and 60% by weight have an e.s.d. less than 1 mu m; (c) adding an additive comprising an anionic polycarboxylate dispersing agent to the suspension of ground material formed in step (b). The process is characterized in that the aqueous suspension formed in step (c) has a pH which lies within the inclusive range 8.5 to 9.8 and in that, following addition of the anionic polycarboxylate dispersing agent in step (c), the suspension is not ground further. Using the method described, suspension can be prepared which are rheologically stable with time, and which contain a relatively high proportion by weight of a finely divided pigment.

摘要： There is disclosed a coated particulate inorganic material, the coating on the particles of the inorganic material comprising a combination of a natural or synthetic polymeric material and a mould release agent. The mould release agent is a fatty acid having from 12 to 20 carbon atoms or a heavy metal or alkaline earth metal salt thereof. The polymeric material is present in the coating in an amount of from 1% to 10% by weight, based on the weight of dry inorganic material. The coated particulate inorganic material is useful as an improved low profile additive for polymeric compositions, and especially for thermosetting polymeric compositions which are specially adapted for forming shaped articles by sheet moulding or by bulk, or dough, moulding processes.

摘要： A method of preparing a waterborne paint composition which includes the steps of:

(a) forming a dispersed suspension in an aqueous medium of inorganic particulate material comprising a composition of a titanium dioxide pigment and a mineral extender having in a paint composition a scattering coefficient less than titanium dioxide, the aqueous medium containing an anionic polyelectrolyte dispersing agent;
(b) concentrating the dilute dispersed suspension formed in step (a) without adding a flocculating agent and without the use of forced evaporation; and
(c) forming a paint composition by adding the concentrated suspension formed in step (b) to a hydrophilic binder, eg. one of the latex emulsions well known in the art, and optionally other paint ingredients.
