摘要:
This invention provides a process for preparing porous polymer structures by a joining of the techniques of thermally induced phase separation and solvent induced phase separation. The process may be used to form both single and multilayer porous articles.
摘要:
A method for preparing a dust-free beaded product from a low melting material is disclosed. The method is particularly applicable to manufacturing processes in which the last step in preparation of a product is a water wash step.
摘要:
Syndiotactic polystyrene can be impact-modified by a blend of (a) polystyrene-hydrogenated polybutadiene block copolymers and (b) one or more core/shell modifiers based on a lightly or non-crosslinked rubber core, and with at least one shell or intermediate shell stage which is predominantly polystyrene, to produce a material of higher impact strength than the better value of either additive singly at the same total impact modifier level.
摘要:
A method of detoxifying biocide which is toxic to aquatic life comprising contacting said biocide with a water soluble organic thiol compound. Applications of the method are primarily for biocide spills or for industrial effluents which comprise biocide and must be detoxified prior to release into the environment, and must pass a photoluminescent bacterial assay. Kits are also disclosed.
摘要:
Binders for ceramic products are provided which are crosslinkable and impart improved tensile strength to ceramic green bodies. The binders are particularly useful in tape-casting processes for the manufacture of thin ceramic sheets which are used as substrates for electronic packaging.
摘要:
The present invention provides a method for making an amine and an alkyl ester, which comprises heating a reaction mixture including a nitrile, an acid, water and a substrate compound, capable of generating a carbonium ion by reaction with the acid, to generate a first reaction intermediate; treating the first reaction intermediate with an acid in the presence of an alkanol to form a second reaction intermediate and an alkyl ester; separating the alkyl ester from the second reaction intermediate; and treating the second reaction intermediate with a base to form the amine.
摘要:
An expandable aqueous coating composition comprising a polymeric binder which including includes a copolymer having a glass transition temperature from -20°C to +60°C and a weight average molecular weight from 20,000 to 500,000 and including expandable particles having a liquid blowing agent contained within a thermoplastic shell. A wallcovering having a 3-dimensionally patterned surface can be made from this coating composition A method for producing the expandable aqueous coating composition is also disclosed.
摘要:
Composites, and a method for preparing composites, are provided. The composites comprise a plurality of domains on the surface(s) of a support material, and the domains contain one or more inorganic compounds. The method comprises contacting a support material with one or more metal-loaded polymers and removing the polymer(s).
