This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.

This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step.

Additionally, the novel resin systems may be partially to fully biobased, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.

The present invention relates to the unexpected discovery of novel multi-aromatic, multi-substituted compounds. In certain embodiments, the compounds of the invention are generated by condensing at least two phenolic- and/or aniline-containing monomers and an aromatic, aliphatic or heteroaromatic aldehyde- and/or ketone-containing monomer. In other embodiments, at least one monomer is isolated from a bio-based resource. In yet other embodiments, the compounds of the invention are bis- or poly-phenolic compounds.

Bio-based, multi-aromatic compounds, and methods of making and using same

A compound is provided according to structure 4, (4) wherein n has a value from 0 to 48 and Z is hydroxyl or a benzene ring bearing substituents R-R, wherein R-Rare each individually selected from the group consisting of H, allyl, alkyl, alkoxy, phenyl, phenoxy, halide, hydroxyl, glycidyl, (meth)acryloyl, 3-(meth)acryloyl-2-hydroxy-1-propoxy, 2,3-epoxypropyl, maleate, and structure (a) wherein at least one of R-R, at least one of R-R, and at least one of R-Ris hydroxyl or an ether or ester derived from it and one of the R-Rgroups is replaced by a direct bond to the CXY group. 

Bisphenol alternative derived from renewable substituted phenolics and their industrial application

Anhydrosugar-based monomers prepared from isosorbide, isomannide, and isoidide and resin systems containing these anhydrosugar-based monomers that are partially to fully bio-based, which may produce materials having properties that meet or exceed the properties of similar petroleum derived vinyl ester resins.
