ORGANOPOLYSILOXANES MODIFIED WITH POLYCARBODIIMIDE

Polycarbodiimide is present as a solid phase in a liquid polyorganosiloxane, preferably being formed therein by mixing a polyisocyanate with the polysiloxane followed by a carbodiimidization catalyst. If the polyorganosiloxane-contains hydroxyl groups it can be chemically bonded to the polycarbodiim...

Beschreibung
Zusammenfassung:	Polycarbodiimide is present as a solid phase in a liquid polyorganosiloxane, preferably being formed therein by mixing a polyisocyanate with the polysiloxane followed by a carbodiimidization catalyst. If the polyorganosiloxane-contains hydroxyl groups it can be chemically bonded to the polycarbodiimide. The stable compositions are suitable for the preparation of molding compositions which can be cured to solid plastic masses, particularly elastomers, of superior properties by adding a curing agent for the polysiloxane.- ' :
