Abstract:
A composition includes a post-cured polymer. A post-cured polymer is formed from a polymer that is a reaction product of a polyfunctional cycloolefin and a metathesis catalyst. The post-cured polymer has a glass transition temperature in a range that is greater than 340 degrees Celsius. An associated article and a method are also provided.
Abstract:
A composition includes a post-cured polymer. A post-cured polymer includes a reaction product of a first cycloolefin and a metathesis catalyst having ruthenium, osmium, or both ruthenium and osmium. The post-cured polymer has a glass transition temperature in a range that is greater than 340 degrees Celsius. An associated article and a method are also provided.
Abstract:
Multi-material retrofitted wind turbine rotor blades include a shell having a leading edge opposite a trailing edge and a structural support member that supports the shell and is disposed internal the wind turbine rotor blade between the leading edge and the trailing edge and extends for at least a portion of a rotor blade span length, wherein the structural support member includes an original structural support portion including a first material and a retrofitted structural support portion extending from the original structural support portion at a joint and including a second material.
Abstract:
A thermosetting polymer material capable of being used in powder coatings. The thermosetting polymer material includes at least one hydroxyl functional aliphatic polycarbonates that is formulated and crosslinked with isocyanates to yield a thermoset organic coating material. These materials provide improved weatherability as compared to prior art powder coating materials while also being less expensive than prior art materials utilizing fluorinated polymers.
