    摘要: Thermoset compositions and methods for forming three-dimensional articles via an additive fabrication process, and articles made therefrom are disclosed herein. In an embodiment, a composition comprises a first network-forming component comprising a TPA-based polyester comprising a backbone and having at least 2 polymerizable groups, one or more first network monomers, and a first network initiator. The backbone of the TPA-based polyester comprises the reaction product of a terephthalic acid and a polyol. The composition may further comprise a second network-forming component.

    摘要: Thermoset compositions and methods for forming three-dimensional articles via an additive fabrication process, and articles made therefrom are disclosed herein. In an embodiment, a composition comprises a first network-forming component comprising a first oligomer comprising a backbone and having at least 2 polymerizable groups, one or more first network monomers, and a first network initiator. The backbone of the first oligomer comprises a polyepoxide based on Bisphenol A, F, or S, a polyepoxide based on hydrogenated Bisphenol A, F, or S, a polycarbonate, or a polyimide. The composition may further comprise a second network-forming component.

    摘要: There is described a process for producing a gel free hyperbranched polyamide polymer having primary amino groups (useful as a crosslinker). The process comprises the step of reacting at least one diamine and at least one unsaturated diester in a molar ratio of diamine to diester greater than 1 but less than 3 (preferably 2.1 to 2.9); to form the polyamide in a two stage reaction Michael addition and then amidation. The diamine in kept in excess with at least 5% of water by total weight of the diamine and diester, a reaction temperature less than the boiling point of the diamine; and is held under reduced pressure (30 mbar to 1 atms). Gelation does not occur even after substantially all ethylenic (-C=C- ) double bonds; and >95% ester [-C(O)=O] groups have reacted. This violates the Flory rules which predict a gel would form based on the number of functional groups present and their degree of conversion.
