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.

Abstract: Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.
