Abstract: The present invention generally relates to curable compositions that include a benzoxazine resin and a polyamide resin, wherein the polyamide resin is a reaction product of (i) a dicarboxylic acid, wherein the dicarboxylic acid includes a non-aromatic, dicarboxylic dimer acid and the mole fraction of the non-aromatic, dicarboxylic dimer acid is between from 0.10 to 1.00, based on the total moles of dicarboxylic acid used to form the polyamide resin; and (ii) a diamine; and wherein the polyamide resin is amine terminated and includes amine end-groups. The curable compositions may be used to produce an article comprising a cured composition wherein the cured composition is the reaction product of the curable composition according to any one of the curable compositions of the present disclosure. The present invention also relates to methods of coating substrates using the curable compositions of the present disclosure.

Abstract: Orthodontic adhesives are claimed which use polymeric filler particles with defined particle size characteristics. The particle size characteristics are controlled such that these adhesives provide comparable mechanical retention and cohesive strength of conventional orthodontic adhesives when used to bond orthodontic appliances to teeth. Because polymeric fillers are generally softer than inorganic fillers, these adhesives are easier to remove from the tooth than conventional adhesives after debonding an orthodontic appliance. Embodiments of the invention include both self-curing and two-part adhesives, packaged adhesive-coated orthodontic appliances, and methods for removing a cured adhesive from a tooth surface.
Abstract translation: 要求使用具有确定的粒度特性的聚合物填料颗粒的正畸粘合剂。 控制粒度特征，使得这些粘合剂当用于将正畸器具粘合到牙齿上时，提供了常规正畸粘合剂相当的机械保持性和内聚强度。 因为聚合物填料通常比无机填料柔软，因此在脱粘矫正器具之后，这些粘合剂比常规粘合剂更容易从牙齿上除去。 本发明的实施例包括自固化和两部分粘合剂，包装的粘合剂涂覆的正畸矫治器，以及从牙齿表面去除固化的粘合剂的方法。

Abstract: A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.
