摘要： The present invention provides an aqueous polymer dispersion which is advantageous in that the coating film as formed therefrom has excellent heat resistance even after being preserved at high temperature, and further has excellent transparency without possibility of becoming white turbid even when the drying temperature during the formation of the coating film is a low temperature of not higher than 100° C., and in that, when used as a release agent, the aqueous polymer dispersion will be an aqueous release agent which undergoes no deterioration of the releasibility even after being preserved at high temperature, and further, has excellent transparency. In the aqueous polymer dispersion, particles of grafted polymer (b) are dispersed in water, wherein grafted polymer (b) includes backbone polymer (a) and a hydrocarbon group with not fewer than 8 carbon atoms in a side chain, with the aqueous polymer dispersion being characterized in that: backbone polymer (a) has a weight-average molecular weight of not less than 20,000, and/or grafted polymer (b) has a viscosity of not lower than 50 mP·s at 60° C. in the form of a toluene solution as diluted to 40 weight %, and further in that the particles of grafted polymer (b) are finely dispersed in water in a state of the volume-average partide diameter less than 0.3 &mgr;m.

摘要： An injection molding binder permitting formation of a molded article incapable of sustaining such defects as a crack or an expansion at the degreasing step and allowing the degreasing treatment to be completed quickly, an injection molding composition, and a method for the production of a sintered member are disclosed. The powder injection molding binder contains a polymer (I) which is obtained by polymerizing a monomer component composed of 50 to 100% by weight of a long side chain-containing monomer and 0 to 50% by weight of other polymerizable monomer. The powder injection molding composition comprises the binder, a binder auxiliary, and a powdery material capable of sintering. The method for the production of a sintered member comprises the steps of injection molding the composition, subjecting the molded mass to a degreasing treatment, and sintering the degreased molded mass.
