A binder component for a feedstock compound for use in a shaping and sintering process comprises b-i) 3 to 70% by volume of at least one first thermoplastic and/or wax-type material, and b-li) 30 to 97% by volume of at least one second thermoplastic and/or wax-type material, based on the total volume of the binder component. The first thermoplastic and/or wax-type material and the second thermoplastic and/or wax-type material differ in at least one property which property is selected from (1) solubility in a solvent, (2) degradability induced by heat and/or a reactant, and (3) volatility. The first thermoplastic and/or wax-type material is less soluble, less degradable or less volatile than the second thermoplastic and/or wax-type material. T.sub.cross is below 120 C., wherein T.sub.cross is the temperature at the intersection between the storage modulus G curve and the loss modulus G curve in a dynamic viscoelasticity measurement of the binder component. The feedstock compound containing the binder component and non-organic sinterable particles is used in an additive manufacturing process, an injection molding process, a pressing process or a casting process.

The present invention is related to an adhesive composition, wherein the adhesive composition comprises a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C.sub.4 to C.sub.10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C.sub.4 to C.sub.10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer, and wherein the polymer blend has a melt viscosity, measured at 190 C. and determined according to ASTM D-3236, of about 1,000 cP to about 10,000 cP; and one or more tackifiers.

Improved casein-based films are produced by adjusting the pH of a film-production suspension. The film-production suspension may contain a casein source, a plasticizer, and optionally a strengthening additive. The adjustment of the pH may be accomplished by the addition of an alkaline additive, such as a base, to achieve a desired pH value. The improved casein-based films have improved physical properties as compared to those produced without a pH-adjusted film-production suspension at least in part due to the chemical and structural changes imparted by the change in pH.
