MODIFIED ETHYLENE-VINYL ALCOHOL RESIN AND PRODUCTION METHOD THEREFOR
A modified EVOH resin comprising aliphatic polyester units, wherein an average chain length of the aliphatic polyester units in the modified EVOH resin is 1.5 or more. A significant decrease in melting point is suppressed in the modified EVOH resin.
DUAL-CURE METHOD AND SYSTEM FOR FABRICATION OF 3D POLYMERIC STRUCTURES CROSS-REFERENCE TO EARLIER APPLICATIONS
A dual-cure method for forming a solid polymeric structure is provided. An end-capped, imide-terminated prepolymer is combined with at least one photopolymerisable olefinic monomer, at least one photoinitiator, and a diamine, to form a curable resin composition, which, in a first step, is irradiated under conditions effective to polymerize the at least one olefinic monomer, thus forming a scaffold composed of the prepolymer and the polyolefin with the diamine trapped therein. The irradiated composition is then thermally treated at a temperature effective to cause a transimidization reaction to occur between the prepolymer and the diamine, thereby releasing the end caps of the prepolymer and providing the solid polymeric structure. A curable resin composition comprising an end-capped, imide-terminated prepolymer, at least one photopolymerisable olefinic monomer, at least one photoinitiator, and a diamine, is also provided, as are related methods of use.
