Abstract
The present invention relates to methods for the production of a resin such as a thermosetting resin, particularly a bioresin, components for use in the methods, and products obtained from the methods. In one aspect the method of forming a resin comprising the steps of: (1) providing an aldehyde-cross-linking agent condensate obtained by reacting a volatile aldehyde with a cross-linking agent; (2) providing a non-volatile aldehyde; and (3) combining the aldehyde-cross-linking agent condensate and the non-volatile aldehyde, thereby forming the resin.
Claims33
A method of forming a resin from an aldehyde oil comprising a volatile aldehyde and a non-volatile aldehyde, comprising the steps of:
- (1) separating the volatile aldehyde from the non-volatile aldehyde;
- (2) reacting the volatile aldehyde with a cross-linking agent to form an aldehyde-cross-linking agent condensate;
- (3) combining the aldehyde-cross-linking agent condensate and the non-volatile aldehyde, thereby forming the resin.
A method for modifying the cross-linking reactivity of a cross-linking agent for resin formation, comprising reacting the cross-linking agent with a volatile aldehyde to form an aldehyde-cross-linking agent condensate which has modified cross-linking reactivity compared with unreacted cross-linking agent.
