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/crosslinker/reactive diluent. 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.

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.

The invention relates to the use of molecularly imprinted polymer(s) or MIPs, of odorous molecule(s), as deodorant agent in particular for selectively trapping molecules that are the cause of human body odour. More particularly by using MIPs which may be obtained via polymerization, preferably via radical polymerization, of a mixture of: i) optionally one or more polymerization initiator(s); ii) one or more functional monomer(s); iii) one or more crosslinking agent(s); and iv) one or more porogenic solvent(s); it being understood that the polymerization a) or b) is performed in the presence v) of one or more “templates” of target molecule(s) responsible for human body odour. Another subject of the invention concerns a process for preparing MIPs as defined previously, MIPs obtained via this process, and a cosmetic composition comprising at least one MIP as defined previously. Unexpectedly, it appears that the MIPs make it possible to specifically trap precursors of odorous molecules and odorous molecules that may be used in cosmetic formulations, especially those that are the cause of the unpleasant odour of sweat.
