Abstract: In accordance with the present invention, there are provided novel heterobifunctional monomers and users for the same. Invention compounds have many of the properties required by the microelectronics industry, such as, for example, hydrophobicity, high Tg values, low dielectric constant, ionic purity, low coefficient of thermal expansion (CTE), and the like. These properties result in a thermoset that is particularly well suited to high performance applications where typical operating temperatures are often significantly higher than those at which prior art materials were suitable. Invention compounds are particularly ideal for use in the manufacture of electronic components, such as, for example, printed circuit boards, and the like.

Abstract: A star-blocked polymeric material based on polyethylene glycol and having a uniform distribution of both hydroxy and amine functional groups throughout the polymeric material is described. The polymeric material, known as HYDRA (hydroxy and amine functionalised resin), is prepared by forming a polyimine compound by reacting an aldehyde and an amine. The polyimine is then reacted with a reducing agent to form a star-blocked polymeric material. HYDRA resins can be used, for example, as solid supports for organic synthesis, for enzymatic assays, for immobilization of biomolecules, for controlled release of drugs, and for chromatographic separations.

Abstract: The present invention relates to a method of producing high-density polyidimide (HPI) films and its production equipment. The production equipment comprises a raw material supplying means, a vacuum cavity, an energy supplier, a clad laminator, and a baked solidified polymer. The foregoing components constitutes the production equipment, using the monomer with the CONH bond or copolymer as raw materials to extract the unsaturated CnullN bond by heat, electrons, light, radiation rays or ions as energy under low-pressure environment, so that the H in vacuum can extract the non-solidified HPI film from the electronic radical covalent polymers and via heat or light to rearrange the structure into a solidified HPI film. By means of the method according to the present invention, the original HPI that is not easily to produce as a film can be easily made in form of a film of HPI polymer on the clad laminator.

Abstract: The novel photo-cross-linkable polymers are suitable as coating materials. The photo-cross-linkable polymers contain a biphenylene unit, which can be dimerized by exposure. Attached to the biphenyl unit are side chains of a polymer with a high temperature resistance and a high chemical stability. Through exposure, the biphenylene units dimerize, whereby the polymers are spatially cross-linked.

Abstract: A nonwoven web and method of preparing a novel nonwoven web of synthetic fiber are disclosed. An aqueous solution amide crosslinked synthetic precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web. The moving foraminous surface is positioned about 10 to about 100 cm from the last gaseous source to contact the threadlines. The fibers have a mean fiber diameter in the range of about 0.1 to 30 Am and are substantially free of shot. The attenuating and drying steps are carried out under conditions of controlled macro scale turbulence.
