Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP).
The method comprises the step of contacting the produced water with polyvinylpolypyrrolidone (PVPP) to remove the contaminants from said water.
Stabilization equipment allows for the application of regenerable stabilizing agents based on PVPP (polyvinylpolypyrrolidone), which are intended to eliminate precursors of colloidal cloudiness of polyphenol components.
This is an alternative or a supplement to a process in which the phenolic compounds are adsorbed onto the insoluble carrier polyvinylpolypyrrolidone (PVPP).
Polyvinylpolypyrrolidone (PVPP), the use of which is provided for in Annex IV(1)(p) and (3)(y) to Regulation (EC) No 1493/1999, is a statistically reticulated polymer of [1-(2-oxo-1-pyrrolidinylethylene).
Proposed is a method of regenerating by oxydation polyvinyl polypyrrolidone charged with phenol-containing substances.
In the beer-making process, the wort is treated with a processing aid which is a composite of Carrageenan and polyvinyl polypyrrolidone (PVPP).
The method according to the present invention can be operated with single use PVPP as well as regenerable PVPP.
The method according to the present invention can be operated with single use PVPP as well as regenerable PVPP.
An infusion of PVPP generally eliminates the substrate of oxidation.
– No PVPP (Polyvinylpyrrolidone) in the wine, as already required by the Official European Organic label.
An infusion of PVPP generally eliminates the substrate of oxidation.
Furthermore, the present method does not require capacious filter hardware for regenerating the PVPP.
The invention relates to a nucleic acid extraction material which comprises at least one ion exchange material and PVPP.
The content of N,N'-divinylimidazolidone in insoluble PVP may not be more than 0.1 %.
Determining that value, the most probably selling price (MPSP), is an art that’s goes beyond straight valuation.

Date of clinical trial start (as defined by the sponsor, e.g., first visit of first patient (FVFP)) 11
Place 2 g of PVPP in a silica capsule with a diameter of 70 mm; dry in oven at 100 to 105 °C for six hours.
Weigh 2 to 3 g of PVPP into a 250 ml conical flask and note the weight, W, accurate to 0.001 g.
Place 0,5 g of PVPP into a round-bottom flask of borosilicate glass placed on a disk with a hole in the middle, with the neck inclined.
Furthermore, the method is very robust and does not require sophisticated, capacious filter hardware for regenerating the PVPP.
The PVPP with improved capability to remove polyphenols may be useful for reducing the formation of colloidal haze in beverages such as beer.
An important part of determining the MPSP involves revealing and reflecting some of the hidden value of your business that doesn’t always show up on the financial statements.
MARINECO LLC, a Russian company founded in 2012 to participate in the Skolkovo TIC PVPP project, is a subsidiary of Applied Technologies Company LLC.
The present invention provides for compositions comprising poly N-vinyl pyrrolidone (PVPP) with improved capability to remove polyphenols, methods of producing and using the same.
Such fining agents as gelatin, casein, isinglass, albumin, egg white, nylon, and PVPP (polyvinyl pyrrolidone) may be used for special purposes, including removal of excess tannin or colour.
For subsequent treatment of clarified juice, the juice is placed in contact with an additive, e.g. PVPP, and filtered in a cross-flow filtration device (11), whereby the heated juice is separated from the additive in the form of a permeate.
