Patent number: 5075417Abstract: Polyester polyols are prepared by reacting a multifunctional adduct (e.g., maleic anhydride (MA)) and tall oil fatty acid, (TOFA), and then esterifying/transesterifying the MA/TOFA reaction product with an excess of aromatic polyester polyols (preferably such polyols are produced from dimethyl terephthalate (DMT) process residue and polyhydric alcohols). The polyester polyols may be used in the manufacture of rigid polyurethane (PUR) and rigid urethane-modified polyisocyanurate (PUR/PIR) foams.Type: GrantFiled: August 31, 1990Date of Patent: December 24, 1991Assignee: Cape IndustriesInventors: John M. Trowell, Billy S. Jessup, Jr.
