Abstract:
Synthesis methods for creating polymeric compounds comprising dihydroxyphenyl derivatives (DHPD), or DHPp i.e. polymers modified with DHPD, with desired surface active effects are described. The polymer backbone of DHPp has structural or performance features that can be tailored to control physical properties of DHPp, allowing it to be useful for different applications i.e. tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.
Abstract:
A hot-melt adhesive composition comprises a blend of at least one acidic polymer and at least one basic polymer. At least one of the polymers is a hot-melt adhesive. Thermally reversible crosslinks are formed between each of the two polymers. These crosslinks impart cohesive strength to the applied adhesive, without sacrificing ease of processing.
Abstract:
A novel thermally reworkable anisotropic conductive adhesive composition for attaching a semiconductor device to a substrate is provided. The composition comprises (a) a thermally reworkable cross-linked resin produced by reacting at least one dienophile having a functionality greater than one and at least one 2,5-dialkyl substituted furan-containing polymer, and (b) at least one electrically conductive material present in an effective amount to provide a conducting medium in only one direction.

Abstract:
PURPOSE: An adhesive film composition for a semiconductor assembly is provided to suppress the generation of burr in dicing by controlling storage modulus before hardening and to prevent damage of products caused by chip crack generated by chipping. CONSTITUTION: An adhesive film composition for a semiconductor assembly includes an elastomeric resin, a film-forming resin, an epoxy-based resin, a phenol hardener, a curing catalyst, a silane coupling agent and inorganic filler. The elastomeric resin contains a hydroxyl group or carboxy group, and an epoxy group. The adhesive film is formed by the composition. A Dicing Die Bonding Film is such that a tackifier layer(2) and an adhesive layer(3) on a base film.
