摘要:
Useful thermoplastic polymer powders are formed by a method comprising: cooling a foam comprised of a thermoplastic foam below the brittleness temperature of the thermoplastic polymer, wherein the foam has an average strut dimension of 10 to 500 micrometers, and comminuting the cooled foam to form a thermoplastic polymer powder. The method allows for the efficient grinding of the thermoplastic polymer having improved morphology and desirable characteristics such as dry flow without flow aids.

摘要:
Disclosed herein are polysilsesquioxane-based anti-reflective coating (ARC) compositions, methods of preparation, and methods of deposition on a substrate. In one embodiment, the polysilsesquioxane of this disclosure is prepared in a two-step process of acid catalyzed hydrolysis of organoalkoxysilane followed by addition of tetralkoxysilane that generates silicone polymers with >40 mol % silanol based on Si-NMR. These high silanol siloxane polymers are stable and have a long shelf-life in polar organic solvents at room temperature. Also disclosed are low refractive index ARC made from these compositions with and without additives such as porogens, templates, thermal radical initiator, photo radical initiators, crosslinkers, Si—OH condensation catalyst and nano-fillers. Also disclosed are methods and apparatus for applying coatings to flat substrates including substrate pre-treatment processes, coating processes and coating curing processes including skin-curing using hot-air knives. Also disclosed are coating compositions and formulations for highly tunable, durable, highly abrasion-resistant functionalized anti-reflective coatings.

Provided are an actinic-radiation-curable resin composition that has high storage stability and that combines high levels of ease of application and adhesion to various substrates and high levels of coating appearance and heat resistance after curing, an actinic-radiation-curable primer for metallization that contains such an actinic-radiation-curable resin composition, and a shaped article including an undercoat layer for metallization that has good adhesion to various substrates. Specifically, an actinic-radiation-curable resin composition is provided that contains an oil-modified alkyd resin and a (meth)acryloyl-containing compound. The oil-modified alkyd resin is prepared using two or more oils having iodine values of 100 or more and has an oil length of 30 to 60, a mass average molecular weight of 200,000 to 1,000,000, and a molecular weight distribution (Mw/Mn) of 50 or more. Also provided is an actinic-radiation-curable primer for metallization that contains the actinic-radiation-curable resin composition.
