TL;DR: The phase behavior and optical and selected mechanical properties of the binary system consisting of isotactic polypropylene (i-PP) and a new sorbitol-based nucleating and clarifying agent, 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl) methylene]-nonitol (TBPMN), were investigated in this article.

TL;DR: The results showed that clear AJ production can be achieved by the clarification step with direct chitosan addition, without the need for enzymatic treatment, and the microbial reduction of A. acidoterrestris during the clarification process was not found to be significant.

TL;DR: In this paper, a process for incorporating a clarifying agent into a semi-crystalline resin is provided whereby a clarifier is selected from compounds having the formula: STR1## wherein p is 0 or 1, m and n are independently 0-3, and R is, at each occurrence, independently selected from C 1-8 alkyl, C 1 -4 alkoxy, hydroxy, halogen, c 1-6 alkylsulfoxy and a 4 or 5 membered alkyyl group forming a carbocyclic ring with adjacent carbon
Abstract: A process for incorporating a clarifying agent into a semi-crystalline resin is provided whereby a clarifying agent selected from compounds having the formula: ##STR1## wherein p is 0 or 1, m and n are independently 0-3, and R is, at each occurrence, independently selected from C 1-8 alkyl, C 1-4 alkoxy, hydroxy, halogen, C 1-6 alkylthio, C 1-6 alkylsulfoxy and a 4 or 5 membered alkyl group forming a carbocyclic ring with adjacent carbon atoms of the unsaturated parent ring, and wherein the clarifying agent is in the form of a powder characterized by a d 97 of 30 microns or less, and a mean particle size of 15 microns or less, is blended with the polyolefin resin, at a temperature above 170° C. until the clarifying agent is dissolved in the molten resin.

TL;DR: In this paper, an aggregated silica gel is described, which has a particle size of 1 to 20 ν, a surface of 200 to 1000 m2/g and a specific pore volume of 0.4 to 2.5 ml/g.
Abstract: The invention relates to an aggregated silica gel which has been produced from silica gel particles having a particle size of 1 to 20 ν, a surface of 200 to 1000 m2/g and a specific pore volume of 0.4 to 2.5 ml/g and a binding agent selected from synthetic or natural phyllosilicate, pyrogenic silicon dioxide and organic polymers soluble in water or dispersible in water. Aggregation takes place by spray-drying a suspension having 1 to 25 % solids. The product is suitable as a matting agent for coatings, as an antiblocking agent for polymer films and as a beer clarifying agent.

TL;DR: In this article, a study to evaluate the efficacy of different clarifying agents, and to find a cheap substitutes for PVP, showed that sago, which is a natural commercial starch preparation, has considerable potential in this respect.
Abstract: Clarification of cashew apple juice by removing phenols and tannins is an important step in cashew apple processing. The common clarifying agent recommended presently is poly vinyl pyrolidone (PVP), a costly chemical. A study to evaluate the efficacy of different clarifying agents, and to find a cheap substitutes for PVP showed that ‘sago’, which is a natural commercial starch preparation, has considerable potential in this respect. Juice clarified by sago was not only qualitatively similar to that clarified by PVP, but also had a higher recovery percentage.
