摘要： A low viscosity unsaturated polyester resin for making buttons is described, which comprises an alkyd prepared by esterification of maleic anhydride and/or acid and/or fumaric acid, optionally together with phthalic anhydride and/or acid and/or adipic, sebacic, azelaic or dodecanedioic acid, with one or more glycols, essentially comprising dipropylene glycol, and further comprises 20-30% by weight of the total resins of an ethylenically unsaturated monomer copolymerizable with the alkyd, essentially chosen among styrene and vinyl toluene, the alkyd having a molecular weight/double bond factor between 300 and 390 and an amount of free functional groups between 80 and 100 mg of KOH per g of alkyd inclusive. The buttons obtainable from said resin are also described. The disc blanks made from said resin have better workability and cause less wear of the tools than those of the prior art and the finished buttons have greater impact strength, and better lustre, greater color stability when exposed to sun light.

摘要： A process for the manufacture of patterned urea thermoplastic molding compound preforms is disclosed where such preforms are suitable for the compressive thermocasting of buttons containing cast holes and displaying an undistorted and consistent pattern. The process utilizes commercially produced molding compound, pigment, adhesives, crystalligerous material plus water which are united to form pliable, self-adhesive aggregates of various colors or hues. These masses are volumetrically measured and/or formed and then assembled in various specific arrangements. This mass is then contained and compressed to expel excess air and cause adhesion of the constituents. The mass is then extruded to a consistently patterned soft rod of a specific diameter. The rod is subsequently sliced to a specific thickness and weight and then dried prior to shipment. In the preferred embodiment of the process, excessive drying is performed by thermal dehydration and necessary minimum water content levels are re-established by specifically prolonged exposure to supersaturated air.
