标题 :Process for preparing hexacis(methoxymethyl)melamine
摘要:A process for preparing hexacis(methoxymethyl)melamine, which comprises the synthesis of hexacis(hydroxymethyl)melamine, the separation of the latter from the residual reaction medium and the etherification thereof to hexacis(methoxymethyl)melamine, the abovesaid synthesis of hexacis(hydroxymethyl)melamine being effected by maintaining the reaction mass at a pH not lower than 7.5, at a temperature not lower than 40 DEG C, and at a minimum stirring speed sufficient to keep in suspension the hexacis(hydroxymethyl)melamine which formed in said synthesis in the form of a crystalline powder easily filtrable and ready for being etherified.

摘要:Novel powder coating compositions containing reactive hyperbranched polymers are disclosed and claimed. Preferred embodiments include powder coating compositions formed from hyperbranched polyesters having terminal hydroxy, carboxy, epoxy, and isocyanate groups. Preferred hyperbranched polyesters are formed from alpha , alpha -bis-(hydroxymethyl)-propionic acid, which act either as crosslinkers, adhesion promotors, or flow and leveling agents. A process for the synthesis of powder coating compositions is also disclosed which involves (a) self condensation of one or more of the multifunctional monomers to form the hyperbranched polymer, optionally, in the presence of suitable reactive end-capping moieties which are described herein; (b) melt blending of the hyperbranched polymer with suitable amounts of one or more of polyesters, epoxy resins, blocked urethane resins, or acrylic resins, a crosslinker, and one or more of suitable additional ingredients including degassers or flow and leveling agents, to form a flake; and (c) grinding and sieving of the flake to form the powder coating composition. These compositions exhibit improved flow and curing properties. These compositions can therefore be formed into thin films and can be cured at low temperatures to form smooth surfaces. Additionally, these films are hard and exhibit enhanced impact resistance properties than the conventional polyester resins. Thus, these powder coating compositions find utilities in automotive, packaging, and appliances.

摘要:The object of the present invention is a novel continuous process for the production of methylol melamines, especially of hexamethylol melamine and of a mixture of higher methylol melamines, wherein a continuous synthesis from a formaldehyde solution and melamine is combined with a continuous drying of the resulting product mixture, whereby a product in the form of a powdery material with a low content of free formaldehyde and water is obtained. Simultaneously, the invention also relates to a process for the production of highly etherified melamine resins based on hexamethylol melamine produced by a process according to the present invention and to the use of hexamethylol melamine produced by a process according to the present invention in a process of the production of highly etherified melamine resins. Particularly, the invention relates to a process of the production of hexamethoxymethylol melamine (HMMM), hexabutoxymethylol melamine (HBMM) and mixed ethers of C1-C5 alkohols on the basis of hexamethylol melamine produced by a process according to the invention.
