Unfortunately, these better performing surfactants are much more expensive to prepare and are often not environmentally friendly
A popular class of such surfactants are fluoroalkyl phosphates, which have the following disadvantages: fluoroalkyl phosphates are difficult to prepare as pure compounds, their preparation is inherently non-selective, resulting in a large number of unfavorable Dialkyl phosphates; second, phosphates are generally prone to degradation by hydrolysis; third, regulatory pressures will generate phase-out of C 8 or the above perfluorinated hydrocarbons and compounds with this substituent, such as CF 3 (CF 2 ) 7 CH 2 CH 2 OPO 3 -2 , which is a substance that is planned to be banned as an additive in the adhesive system in 2015

Embodiment 1
[0042] Example 1 – Preparation of paint compositions containing anti-blocking additives
[0043] Intermediate 1 (0.0626 grams) was mixed with the composition of Comparative Example 1 (100 grams) using a Miller GyroMixer for 9 minutes in a 120 ml plastic container.
Embodiment 2
[0044] Example 2 – Preparation of paint compositions containing barrier additives
[0045] The procedure for preparing the paint composition of Example 2 was essentially the same as described for the preparation of Example 1, except that 0.1251 grams of Intermediate 1 was used.
[0046] The final pH of the control and example paints was about 8.9. Store paint at room temperature for 48-72 hours before application.
Embodiment 3-6
[0047] Example 3-6 – Preparation of paint compositions containing anti-blocking additives
[0048] Examples 3-6 were prepared by adding Intermediate 1 to the composition of Comparative Example 2 as described in Example 1 .

Abstract
The present invention is a composition comprising an aqueous dispersion of a binder and a salt of the following fluoroalkyl phosphonic acid: wherein n, q, and p are as described herein. The composition of the present invention is useful as a block additive in coating compositions.
Description
Background technique [0001] The present invention relates to a composition comprising a fluoroalkyl phosphonate and a binder. [0002] Block resistance is the ability of a paint not to stick to itself. For example, good blocking resistance enables a door not to stick to a door frame or a window not to stick to its frame. Antiblocking properties in waterborne paint formulations are achieved by antiblocking additives such as fluorinated alkyl surfactants containing high concentrations of fluorine. These highly fluorinated compounds in architectural coating compositions generally perform better than compounds containing lower fluorine content. Unfortunately, these better performing surfactants are much more expensive to manufacture and tend to be environmentally unfriendly. A popular class of such surfactants are fluoroalkyl phosphates, which have the following disadvantages: fluoroalkyl phosphates are difficult to prepare as pure compounds, their preparation is inherently non...
