Patent ID: 7828991

Claim:
A process for preparing renewable resource based polyether polyols having an OH number of from 20 to 130 and a functionality of about 2.8 to about 4.5, which comprises (1) reacting (a) a mixture having an OH number of from about 180 to about 300, an average functionality of about 2.8 to about 4.5, which comprises (i) from 5 to 25% by weight of 3-pentadecadienylphenol, (ii) from 5 to 15% by weight of 3-pentadecadienyl-recorcinol, (iii) from 1 to 5% by weight of 2-methyl-3-pentadeca-dienylrecorcinol, and (iv) from 60 to 80% by weight of phenolic OH-functional organic compounds having a number average molecular weight of greater than 700, with the sum of the %'s by weight of (i), (ii), (iii) and (iv) totaling 100% by weight of the mixture (a); with (b) one or more alkylene oxides, optionally, in the presence of (c) one or more catalysts, with the weight ratio of components (a) to (b) ranges from 50:50 to 5:95.
