Biomass derived methyl methacrylate and corresponding manufacuring method, uses and polymers

Abstract

The invention relates to methyl methacrylate characterized in that at least one portion of the carbons thereof is biologically sourced and, more specifically, in that it contains between 0.2×10−10 and 1.2×10−10 wt.-% of 14C in relation to total carbon weight according to the ASTM D6866 standard. The preparation method comprises the use of acetone cyanohydrin as a raw material, said acetone cyanohydrin being obtained by condensing cyanohydric acid on acetone, and the methyl methacrylate is prepared using a process involving the addition of methanol. According to the invention, at least one from among the acetone, cyanohydric acid and methanol is obtained by means of a reaction or series of reactions involving the biomass.
