Carbodiimide compounds, polymers containing same and coating compositions containing said polymers

摘要

Carbodiimide compounds having the following structural formula are claimed: <IMAGE> (I) Z being selected from the group consisting of the following moieties: <IMAGE> (a) <IMAGE> (b) <IMAGE> (c) wherein R1 represents an alkylidene radical; R2 represents hydrogen or an alkyl radical; R3 represents an alkyl radical, an aromatic hydrocarbon moiety or a cycloaliphatic hydrocarbon moiety or substituted derivatives thereof; R4 represents an aromatic hydrocarbon moiety; R5 represents an alkyl radical; and x is an integer ranging from 1 to 6. Polymers containing moieties of at least two such carbodiimide compounds depending therefrom are also claimed and are useful in the formulation of coating compositions which harden or cure at low temperatures.
