    摘要: An abrasive composition comprising non-polymeric organic particles that is useful for chemical mechanical planarization (CMP), and which can widely be used in the semiconductor industry. The inventive compositions preferably comprise soft water in combination with 0.001–20 w/w % of non-polymeric organic particles, 0.1–10 w/w % of an oxidizing agent, 0.05–10 w/w % of a chelating agent, 0.01–10 w/w % of a surfactant, and 0–10 w/w % of a passivation agent at a pH in the range of 2–12, wherein said percentages are w/w (weight/weight) percentages, based on the total weight of said compositions. The abrasive compositions provide an efficient polishing rate, excellent selectivity and good surface quality when utilized as a new abrasive composition in CMP applications.

    摘要: A one-step, in-situ, process for producing a high solids content emulsion or dispersion of partially or totally crosslinked urea formaldehyde (UF), melamine formaldehyde (MF), or melamine urea formaldehyde (MUF) resin droplets or particles, by forming a reaction mixture of (i) aqueous formaldehyde (formalin), (ii) at least one water-soluble protective colloid, (iii) water and (iv) optionally a surfactant, and mixing the reaction mixture in a reaction vessel; optionally adjusting the initial pH of the reaction mixture according to a desired value as needed; adding (i) urea or substituted urea, (ii) melamine or substituted melamine, or (iii) a mixture thereof, to the reaction mixture; and heating the reaction mixture to a temperature at which condensation takes place between the (i) urea or substituted urea, (ii) the melamine or substituted melamine, or (iii) the mixture thereof, and the formaldehyde to form a urea formaldehyde, melamine formaldehyde or melamine urea formaldehyde resin, and holding the reaction mixture at that temperature or a higher temperature, under mixing, for a period of time sufficient to achieve a desired degree of crosslinking in said urea formaldehyde, melamine formaldehyde or melamine urea formaldehyde resin; and cooling the reaction mixture. The droplet or particle size of the resulting resin dispersion can be controlled and adjusted by way of the present technique to the application requirements.

    摘要: Phenolic resins and processes of making these phenolic resins that are useful for making binders for mineral wool insulation products are disclosed. The addition of a boron salt early in the process of making these phenolic resins leads to enhanced properties such as a reduction in the amount of tetradimers and an improvement in the stability of both the base resin and the pre-react.
