Abstract: A polymer substrate, such as a polymer particle, is formed from a carboxyl functional monomer. In an example, the carboxyl functional monomer has a protection group in place of the OH of the carboxyl group. Once the monomer is polymerized, such a protection group can be removed, providing a polymer network with carboxyl functional sites. Such sites can be used to attach other functionality to the polymer substrate.

Abstract: The present invention is directed towards a method of stabilizing thermosetting foam blends such as polyurethane poly blends containing a blowing agent with negligible (low or zero) ozone-depletion and low GWP based upon unsaturated halogenated hydroolefins in which one or more ester is added to the thermosetting foam blends. The thermosetting foam blends typically in clued: polyol(s); surfactant(s); catalyst(s); flame retardent(s); organic acid inhibitor(s)/stabilizer(s); carbon dioxide generating agent(s). The addition of the one or more esters to the thermosetting foam blends was unexpectedly found to result in blends which were stable over time and the resulted foams have a uniform cell structure with little or no foam collapse.

Abstract: Silica aerogels with improved properties are disclosed together with methods for synthesizing such aerogels. The improved properties include lower thermal conductivity (better insulating capacity), lower acoustic velocity, lower dielectric constant and improved ductility. Greater tunability of the refractive index can also be achieved. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation or aerogel structures. Generally speaking, the improvements arise from control of the synthesis to create a morphology of primary clusters and diverse-sized secondary clusters of dense silica aerogels separated by less densely packed regions. By providing a broader range of secondary clusters and/or pore sizes and loose connectivity between clusters, reductions can be achieved in thermal conductivity and flexural modulus.
