Cyclic olefin copolymer (COC) is useful as a build material for 3D printing, especially desktop 3D printing.

COC polymer compounds for 3D printing

Copolymers of a polyvinyl butyral backbone with polylactic acid grafts and their compounds are disclosed, which can be used to produce clear, flexible and ductile bio-based films. The copolymers are amorphous and have been shown to maintain clarity, flexibility, and ductility after continuous exposure to thermal aging at 80&#xb0; C. for one week.

Polyvinyl butyral-g-polylactide copolymer

Aliphatic polyimides are synthesized by a reaction of 2 moles of an unsaturated monoanhydride or an unsaturated diacid with both one mole of a diamine and one mole of a monoamine. Imidization of intermediates so formed from those reactions resolve to 6 possible bicyclic imidic structures bridged by monoamidic or saturated hydrocarbon spans, more likely the latter. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.

Aliphatic polyimides from unsaturated monoanhydride or unsaturated diacid reacted with both monoamine and diamine

Aliphatic polyimides are synthesized by a 2:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.
