Crosslinked Internal Alkyne-Based Stereo Elastomers: Polymers with Tunable Mechanical Properties

New methods to introduce and control polymer network crosslinking and improve mechanical properties of the resulting materials have been investigated extensively. Common methods to enhance the mechanical properties of elastomers include "vulcanization"by

Production Of Terephthalic Acid Via Reductive Coupling Of Propiolic Acid Or Propiolic Acid Derivatives

A method of making terephthalic acid via reductive coupling of two molecules of propiolic acid or propiolic acid derivatives is presented. The reductive coupling can be catalyzed by compounds comprising metals, and propiolic acid or propiolic acid derivatives can be produced from acetylene and carbon dioxide. At least 4 of the 8 carbons in the terephthalic acid are non-fossil-derived.

A method for preparing sodium acrylate-d3, a useful and stable precursor for deuterated acrylic monomers

A convenient and economical method for converting propiolic acid to sodium acrylate-d3 is described. Successive D/H exchange of the alkyne proton of sodium propiolate (prepared from propiolic acid) using D2O affords sodium propiolate-d having up to 99 at.% D. Sodium propiolate-d can be partially reduced to sodium acrylate-d3 with 90% conversion and 89% yield using D2 and the Lindlar catalyst, with control of reaction parameters to maximize conversion while minimizing over-reduction. Copyright 2011 John Wiley & Sons, Ltd. A three-step synthetic route for preparing sodium acrylate-d3 in high yield and high isotopic purity from propiolic acid is described. Copyright
