Problems solved by technology

However, the use of these solvents is undesirable due to their emission of volatile organic compounds (VOCs), which are generally harmful to humans, and therefore require removal
To remove the solvent consumes process time, thereby increasing the cost, and when the solvent is removed, it will cause the viscosity problem of the composition

Embodiment 1

[0019] The reaction product was prepared by the same procedure as described in Comparative Example 1, except that 169 grams of methyl methacrylate was first mixed with polyphosphoric acid before adding 2-hydroxyethyl methacrylate. On a basis excluding methyl methacrylate, the reaction product contained 47.0% by weight monoester and 9.43% by weight diester, corresponding to a monoester:diester molar ratio of 7.64.

Embodiment 2

[0021] The reaction product was prepared by the same procedure as described in Comparative Example 1, except that 302 grams of methyl methacrylate was first mixed with polyphosphoric acid before adding 2-hydroxyethyl methacrylate. On a basis excluding methyl methacrylate, the reaction product contained 47.9% by weight monoester and 7.58% by weight diester, corresponding to a monoester:diester molar ratio of 9.69.

Embodiment 3

[0023] The reaction product was prepared by the same procedure as described in Comparative Example 1, except that 418 grams of methyl methacrylate was first mixed with 200 grams of polyphosphoric acid before adding 218 grams of 2-hydroxyethyl methacrylate. On a basis excluding methyl methacrylate, the reaction product contained 51.0% by weight monoester and 7.24% by weight diester, corresponding to a monoester:diester molar ratio of 10.8.

Abstract

The present invention relates to a process for providing improved low VOC polymerizable compositions containing phosphoalkyl (meth)acrylate monomers which are synthesized by the reaction of a hydroxyalkyl (meth)acrylate with polyphosphoric acid (PPA).

Description

technical field [0001] The present invention relates to a method for providing improved low VOC polymerizable compositions comprising phosphoalkyl(meth)acrylate monomers obtained by ( It is synthesized by reacting hydroxyalkyl methacrylate with polyphosphoric acid (PPA). Background technique [0002] People spend a lot of time indoors, which makes people more concerned about the quality of the air we breathe when we are inside buildings. Products and materials in homes and office buildings emit pollutants and chemicals, many of which pose health problems. One class of pollutants that has received particular scrutiny is volatile organic compounds (VOCs). These compounds are ubiquitous, and attention has been paid to discovering the source of VOCs and reducing their emissions. [0003] In everyday life, VOCs are emitted from a surprising number of articles, especially virtually all resin-based man-made materials. Varnishes and coatings have previously been used to provide ...
