Abstract:
1. A method of producing a transesterified polyol having increased functionality comprising: providing a first compound having multiple functional hydroxyl groups; a blown vegetable oil having fatty acids in triglyceride form chosen from the group consisting of a blown soybean oil, a blown rapeseed oil, a blown cottonseed oil, a blown palm oil, a blown safflower oil, a blown sunflower oil, a blown canola oil, a blown linseed oil and a blown coconut oil; and a transesterification catalyst; forming a combination that includes the first compound having multiple functional hydroxyl groups, the transesterification catalyst, and the blown vegetable oil; heating the blown vegetable oil and the first compound having multiple functional hydroxyl groups; and forming the transesterified polyol that is derived from the blown vegetable oil and having increased functionality compared to the blown vegetable oil by transesterification between one of the fatty acids of the heated blown vegetable oil and one of the functional hydroxyl groups of the heated first compound having multiple functional hydroxyl groups.
