  • Patent number: 9139681
    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.
    Type: Grant

  • Publication number: 20050010069
    Abstract: Ozonolysis is a well known process involving reacting ozone with alkene compounds, for example in unsaturated vegetable oils or free fatty acids and esters thereof, to form ozonolysis products (e.g. ozonides). The invention concerns ozonolysis of unsaturated oils (e.g. unsaturated plant oils and/or unsaturated animal oils) in the presence of a participating co-reactant to form reaction products particularly suitable for use in the formation of resins.
