Abstract: Aspects of the present invention relate to polymers, and particularly to farnesene polymers functionalized with one or more oxirane groups and, optionally, one or more hydroxyl groups. According to one aspect of the invention, provided is an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The epoxidized farnesene polymer has at least one of a side chain or a main backbone functionalized with at least one oxirane group and, optionally, at least one terminal end functionalized with a hydroxyl group. In accordance with another aspect of the invention, a method is provided for preparing an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The method includes epoxidizing a farnesene polymer, which may optionally contain one or more terminal hydroxyl groups, to functionalize at least one of a side chain or a main backbone of the farnesene polymer with an oxirane group.

Abstract: A terminal hydroxyl functionalized polyfarnesene is provided. The polyfarnesene has more than two terminal hydroxyl groups per molecule, on average, based on the number average molecular weight. The polyfarnesenes may be homopolymers or copolymers of farnesene. Also provided is a method of making these polyfarnesenes having more than two hydroxyl groups per molecule. A composition for making a polyurethane comprising a diisocyanate and the terminal hydroxyl functionalized polyfarnesene is also provided.

Abstract: Curable compositions are prepared using polyisocyanates, hydrophobic hydroxyl-terminated polymers (such as hydroxyl-terminated polyfarnesenes and hydroxyl-terminated polydienes) and organically-modified nanoclays, optionally in combination with chain extenders and/or urethane catalysts. When cured, the compositions yield polyurethane-based sealants useful in insulating glass units which have improved (lowered) moisture vapor transmission rate values as a consequence of the inclusion of the organically-modified nanoclays.
