Assignee: EASTERN MICHIGAN UNIVERSITY
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 24:
25. A method of additive manufacturing, the method comprising:
applying a first layer of an additive manufacturing component;
applying a polymeric composition on the first layer, wherein applying the polymeric composition comprises:
(a) applying a UV-curable composition on the first layer, the UV-curable composition comprising: (i) a Michael-addition (MA) acceptor compound comprising at least one MA acceptor functional group, (ii) a Michael-addition (MA) donor compound comprising at least one MA donor functional group, (iii) a photo-latent base initiator, and (iv) at least one secondary curing compound comprising a silane compound comprising at least two hydrolysable groups, and
(b) exposing the UV-curable composition to UV radiation (i) to form a base catalyst from the photo-latent base initiator and (ii) to subsequently catalyze with the base catalyst (A) MA polymerization between MA acceptor functional groups and MA donor functional groups, (B) anionic polymerization between MA acceptor functional groups, and (C) optionally polymerization of the at least one secondary curing compound, thereby forming the polymeric composition; and

applying a second layer of an additive manufacturing component on the polymeric composition.
