摘要:
An electronic device provided includes an electronic device body and a protective sheet protecting a surface of the electronic device body. The protective sheet includes a multilayer structure including at least one base (X), at least one layer (Y), and at least one layer (Z). The layer (Y) contains an aluminum atom, and the layer (Z) contains a polymer (E) containing a monomer unit having a phosphorus atom. The multilayer structure includes at least one pair of the layer (Y) and the layer (Z) that are contiguously stacked. This electronic device is adapted to maintain the gas barrier properties of the protective sheet at a high level even when subjected to physical stresses.
摘要:
Non-halogenated monomers that can be polymerized into flame retardant polymers, and processes to produce the monomers and polymers is provided. In a simplest aspect, there is provided a monomer composition that can comprise a) a group derived from one of a (meth)acrylic acid, (meth)acrylamide, or vinylbenzene, b) a polyphosphate moiety, and c) an amine species. In the monomer composition, the ethylenically unsaturated monomer of (a) is covalently bonded directly or through a linking group to the moiety of b), forming a precursor monomer unit. The amine species of c) is in complex with the precursor monomer unit. The polymer can be a homopolymer of the monomer composition, or a copolymer of the monomer composition having varying a), b) and c). In one embodiment, the polymer can additionally comprise ethylenically unsaturated monomers not covalently bonded to a polyphosphate moiety and/or can be cross-linked with a cross-linking agent such as resorcinol.
摘要:
The present invention relates to a composition of a stable aqueous dispersion of polymer particles comprising structural units of a) vinyl acetate; b) a vinyl ester of a branched carboxylic acid monomer; and c) a phosphorus acid monomer. The composition of the present invention provides vinyl ester/phosphorus acid based polymer particles that improve hiding efficiency in pigmented coatings formulations.
