  • Patent number: 11319421
    Abstract: The present invention relates to a microfluidic flow process for making monomers, monomers made by such processes, and methods of using such monomers. In such process, microfluidic reaction technology is used to synthesize cyanation reaction products orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does require strictly regulated, highly toxic cyanogen chloride. Thus the aforementioned process is more economically efficient and reduces the environmental impact of thermosetting resin monomer production, and produces thermosetting resin monomers in greater purity than obtained through typical processes.

    Abstract: A curing agent for epoxy resin has one or more five- or six-membered aromatic rings, and substituted on the one or more five- or six-membered rings at least two functionalities reactive with the epoxy selected from the group consisting of hydroxyl, amine, imidazole, azine, hydrazide, anhydride, and Lewis acid groups. Choice of functionality can provide a mixed polymer network, one with a more densely cross-linked polymer structure having a high Tg, and the other with a more linear polymer structure to contribute to stress reduction.

  • Publication number: 20120046412
    Abstract: Non water-soluble polymers with a comb structure and a (meth)acrylic skeleton on which are grafted side chains containing at least one hydrophobic monomer of the styrene or (meth)acrylic ester type on C1 to C4, and at least one hydroxy or methoxy polylakylene glycol monomer. The levels of monomers are such that the polymer is amphiphilic because it is both rich in hydrophobic monomer and polylakylene glycol monomer. These products, used in paper coating dispersions, enable an increase in their Brookfield™ viscosity, a reduction in their ACAV viscosity, and an improvement in their water retention, which makes them particularly well suited for dry extract and/or high deposit speed coatings.

  • Patent number: 8106121
    Abstract: The invention relates to graft polyols with a bimodal particle size distribution and a total solid content of between 5 and 65 wt. %. Said polyols contain small particles with a particle diameter of between 0.05 and 0.7 ?m and large particles with a particle diameter of between 0.4 and 5.0 ?m, whereby the peaks of the large and small particles measured during a representation according to the light-scattering analysis method do not overlap. The total solid content with the defined particle sizes consists of a volumetric fraction of between 5 and 45% small particles and a volumetric fraction of between 95 and 55% large particles, said volumetric fractions totalling 100%. The invention also relates to a method for producing graft polyols of this type and to the use thereof for producing polyurethanes.
