A contract emulsion you may get away with it but adding pva to a Acrylic paint is only going to upset the chemistry of the paint and no doubt affect its performance, if you need to add stuff to a paint perhaps it is the wrong product and a slippery slope one thinks ?
Formula. Following is the formula for calculating present value of an annuity: PVA = P * ((1 - 1 / (1 + i) n) / i) where, PVA = Present value P = Periodic payment amount n = Number of payments i = Periodic interest rate per payment period; This is derived from nominal annual rate using the formula shown in the calculator for periodic interest rate. For annuities where the payment is made in ...

According to "House Paints, 1900-1960: History and Use By Harriet A. L. Standeven" PVAc was used in the formulation of emulsions. And in fact I found a seller of paint resins still retailing it. The book points out that pure PVAc is brittle and embrittles with age and so plasticisers are were added to actually weaken the resin to allow it to ...
When PVA is incorporated into emulsion coatings and adhesives, it is normally converted to polyvinyl alcohol first, which is a water-soluble polymer. This is done by means of partial hydrolysis . The result is stronger and more durable than if the compound had been isolated and used in its raw form.
In its original formulation, it was a casein glue, but about 20 years ago, the Borden Co. changed the formula to a PVA emulsion. Recently, there has been an additional change. Now, unlike other PVA emulsions that are soluble only in PVA solvents after they are dried, the only solvent recommended by Borden, Inc. for Elmer's Glue All is water.
Polyvinyl acetate, a synthetic resin prepared by the polymerization of vinyl acetate. In its most important application, polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it is also used in adhesives. Learn more about polyvinyl acetate in this article.
Polyvinyl acetate ( PVA, PVAc, poly (ethenyl ethanoate) ), commonly known as wood glue, white glue, carpenter's glue, school glue, or Elmer's glue in the US, is a widely available adhesive used for porous materials like wood, paper, and cloth. An aliphatic rubbery synthetic polymer with the formula (C 4 H 6 O 2) n, it belongs to the polyvinyl ...
Many PVA emulsion glues are nowadays based on copolymers, at least in part. Creep can also be reduced by adding a vinyl methyl ether/maleic an hydride copolymer. The thickening agents such as starches, starch-ethers, methyl cellulose or sodium carboxymethyl cellulose and also anti ing compounds are frequently added to the emulsions.
The invention concerns a method for preparing an anti-ing emulsion from a silicon anti-ing phase, containing at least a linear polyorganosiloxane oil and at least one mineral filler, to be emulsified in an aqueous phase containing polyvinyl alcohol. The invention is characterised in that the silicon anti-ing phase is introduced into the aqueous phase in several steps, the method ...
Polyvinyl alcohol is a man-made or synthetic polymer. PVA polymer molecule contains vinyl and alcohol groups. It is a very useful polymer due to its adhesive properties. PVA is water soluble, crystalline and flammable in nature. Presence of alcohol group in it makes it flammable.
The present value of an annuity (PVA) is the current worth of regular cash flows to be received at a specific date in the future based on the interest rate, which is also called the required rate of return. Coupon payments of a fixed-rate bond and amortized loans are common examples of annuities. Formula

Polyvinyl acetate and polyvinyl alcohol. Polyvinyl acetate (PVA) and polyvinyl alcohol (PVOH) are further examples of ethylene copolymers. PVA is used as an emulsion adhesive for bag, sack and carton making. PVOH is produced by hydrolysis of PVA and the strong hydrogen bonding imparted by the –OH groups means that pure PVOH is water soluble.
