    Abstract: The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved by incorporating amide-extended maleimides into an adhesive formulation. Amide-extended maleimides described herein can be used to toughen bismaleimide thermosetting materials without sacrificing any thermal stability. Amide-extended maleimides are readily prepared by reacting a bismaleimide with an appropriate amine via the well-known Michael addition reaction. Acylation of the resulting secondary amines provides the amide-extended maleimide. The acylating agent can also be used to introduce polymerizable functional groups into the backbones of these thermoset monomers. Amide-extended acrylate and methacrylate monomers can also be prepared.

  • Patent number: 8124687
    Abstract: A polymeric material comprised of (i) at least one random copolymer comprised of ethylene oxide and one or more other alkylene oxide(s) and (ii) at least one non-random polymer comprised of one or more poly(alkylene oxide)s has been discovered. Preferably, it is a polymer alloy. Alkylene oxide homopolymers or block copolymers may be the non-random polymer. In a related discovery, an adhesive material can be made by suspending (a) particles in (b) a matrix of at least one poly(ethylene oxide) copolymer of ethylene oxide and propylene oxide, or a combination thereof. The handling characteristics may be adjusted for different utilities (e.g., from runny oil to hard wax). Applications include use as adhesive, cohesive, filler, lubricant, surfactant, or any combination thereof. In particular, the hard materials may be used for cleaning or waxing.

  • Publication number: 20110245431
    Abstract: The present invention provides a brominated epoxy resin, which has a molecular segment of low polarity in the polymer chain, while the molecular segment of low polarity is attributed to the symmetric or saturated cyclic alphatic molecular structure with low “molecular dipole moment” characteristics; making a printed circuit board for high frequency signal transformation applications needs a proper copper clad laminate which processes the properties of a low dielectric constant and of a low dissipation factor; a copper clad laminate can meet above requirements by using the inventive resin as a laminate binder. The inventive resin is prepared by the following steps: 1. Reacting a 2,6-disubstituted mono-phenol compound (A) with an aldehyde or a cyclic diene compound (B), so as to obtain a bisphenol compound (C) having a high symmetry or saturated aliphatic heterocyclic structure; 2.
