【 摘 要 】

Abstract

The cover picture shows a GreenCaps microcapsule breaking and releasing encapsulated glycerol after the organosilica microspheres are sprayed from a pressurized polyurethane foam can. This shows how glycerol acts as a solid curing agent, promoting crosslinking of partially polymerized diphenylmethane diisocyanate. For more details, see the Full Paper on 10.1002/open.201402107 ((p. 120 ff.))
