The analysis on the reason of fracture of die indicated that bended,massive and semi-network metastable eutectic carbides as well as bended and chain secondary carbides in the raw material would lead to inhomogeneous structure and stress concentration in the die and induce the early fracture of die.

The difference properties of porcine acellular dermal matrix crosslinked by epoxy compound and carbodiimide

Catalyzed by compound containing PO covalent bond, carbodiimide oligomer was synthesized from MDI, then intermediate was capped by compound containing hydroxyl, in the end, MDI based hydrolyze resistant reagent was produced.

A series liquefied MDI (carbodiimide modified MDI) containing different amount of carbodiimide and uretoinime were synthesized by controlling carbodiimide conversion, samples were analysized by gel chromatogram, by the same time, all peaks in GPC spectrum were detected and determined their corresponding component by infrared spectrum.
