Abstract:
A dual curable composition is provided, comprising a compound represented by formula (I): (acrylate)a-(A)-(silane)b (I) in which a and b are identical or different and are each represented by an integer greater than or equal to 1; and wherein the dual curable composition is radiation curable and/or moisture curable. The moiety A comprises at least one of an aliphatic hydrocarbon, a cycloaliphatic hydrocarbon, an aryl moiety, an ether, an ester, an amide, a urethane, a urea, a hydroxyl group-containing organic moiety, an acrylic oligomer, an epoxy oligomer, a urethane oligomer, a polyester oligomer, or mixtures thereof, and the dual curable composition has a molecular weight greater than or equal to 300.
Abstract:
The invention relates to a flame-retardant polyamide composition comprising a polyamide with a melting temperature higher than 265° C. and ammeline and/or ammelide, in which the ammeline and/or ammelide is obtainable by a biocatalytic process from melamine in an aqueous reaction mixture comprising a biocatalyst, wherein melamine is converted into ammeline and optionally further into ammelide.
Abstract:
A phenol-modified polyorganosiloxane suitable as a modifier for an organic resin, in which a platinum metal content is reduced, and the yellowing is reduced, a method for preparing the same, and a modifier for an organic resin containing the same are provided. The phenol-modified polyorganosiloxane is a compound of formula (I), having a platinum metal content of 0.9 ppm or less. The phenol-modified polyorganosiloxane can be prepared by subjecting a phenol compound substituted with an alkenyl group of formula (IV) and a polyorganohydrogen siloxane of formula (V) to a hydrosilation reaction in the presence of a platinum-based catalyst applicable to a homogenous system, and subsequently, reducing the platinum metal content of the resulting product to 0.9 ppm or less by conducting one or more filtration procedures selected from the group consisting of filtration conducted where activated carbon is added, filtration conducted by using a filter comprising activated carbon, and filtration conducted by using a filter capable of adsorbing cations, alone or in combination.
Abstract:
The present invention provides a process for forming an article from a diene rubber, comprising: providing a raw diene rubber substance comprising 1,2-polybutadiene rubber component; adding to the raw diene rubber substance a peroxide as a vulcanizing agent; softening the raw diene rubber at a first temperature of not more than 200° C.; vulcanizing the diene rubber at a second temperature of not more than 200° C., with contacting the diene rubber to an ambient atmosphere; and forming from the vulcanized diene rubber an article.
