  The present invention relates novel furan based amine cross-linkers with improved thermomechanical and water barrier properties. The novelty of this invention is the use of aromatic, and hydrophobic aliphatic aldehydes to bridge two furfuryl amines, which yields a diamine or tetra amines with a significantly enhanced hydrophobic character. These diamine cross-linkers exhibit enhanced water barrier properties and thermomechanical properties when cured with both commercial and synthetic epoxies.

  Bismaleimides (BMI) exhibit excellent heat resistance (high Tg and high resistance to thermal decomposition) compared to epoxy resins and phenolic resins, and therefore, in recent years, more attention is paid to bismaleimides as a resin material for the next-generation devices represented by SiC power semiconductors, in addition to the investigation on the use of bismaleimides for electronic material applications. As such, conventional BMI's are known as highly heat-resistant resins; however, there is a demand for a resin having higher heat resistance for advanced material applications and the like. Thus, an object of the invention is to provide a novel maleimide compound having superior heat resistance. Disclosed is a substituted or unsubstituted allyl group-containing maleimide compound having a structure with three or more benzene rings, having one or more groups each having a substituted or unsubstituted allyl group, and having one or more maleimide groups.

  A pinene-derived diisocyanate compound, a process for forming a pinene-derived diisocyanate compound, and an article of manufacture containing a polyurethane polymer are disclosed. The process for forming the pinene-derived diisocyanate compound includes oxidizing the pinene to form a pinene-derived ketone compound, converting the pinene-derived ketone compound to a diamine compound in subsequent reaction steps, and reacting the diamine compound with phosgene to form the pinene-derived diisocyanate compound. The polyurethane polymer is synthesized in a reaction between a pinene-derived diisocyanate compound and a polyol.

  Tertiary amine catalysts having isocyanate reactive groups that are capable of forming thermally stable covalent bonds able to withstand temperatures up to 120° C. are disclosed. These catalyst can be used to produce polyurethane foam having the following desirable characteristics: a) very low chemical emissions over a wide range of environmental conditions and isocyanate indexes (e.g. indexes as low as 65 but higher than 60) while meeting all physical property requirements; b) sufficient hydrolytic stability to maintain the catalyst covalently bound to foam without leaching of tertiary amine catalyst when foam is exposed to water or aqueous solutions even at temperatures higher than ambient (temperature range 25° C. to 90° C.); and c) stable contact interface between the polyurethane polymer and other polymers (for example polycarbonate) with minimal migration of tertiary amine catalyst from polyurethane polymer to other polymers yielding no noticeable polymer deterioration at the point of contact even under conditions of heat and humidity.
