摘要： A powered mixing unit adapted for emulsifying water extended polyester resins to such degree that during and subsequent to curing the water extender in the finally molded product will be easily and readily released creating a three-dimensional opencelled resin network. To achieve this desired water release the majority of emulsion particles are ideally sized between about 1 and 5 microns and in the typical rotary mixer operating between about 1,750 and 5,000 rpm such sizing may be accomplished by providing an impeller that occupies between about 3 and 10 percent by volume of the mixing chamber. Similarly, the impeller should be so shaped that only a moderate shear is produced in the chamber during operation.

摘要： A METHOD OF EASILY REDUCING THE WATER CONTENT OF CAST OR MOLDED WATER EXTENDED POLYESTER ARTICLES RELIES PRINCIPALLY UPON CONTROLLING THE PARTICLE SIZE IN THE RESIN/WATER EMULSION FROM WHICH THE ARTICLE IS MOLDED. SUCH CONTROL MAY BE IMPLEMENTED THROUGH THE EMPLOYMENT TO SURFACE ACTIVE AGENTS AND AGGGREGATES IN THE MOLDING COMPOSITION AND THE CAREFUL CONTROLLED MIXING OF THE COMPOSITION. REGARDLESS OF THE TECHNIQUE EMPLOYED, THIS INVENTION CONCEPTUALLY INCLUDES THE PRODUCTION OF A WATER EXTENDED POLYESTER THREE-DIMENSIONAL OPEN MOLDED NETWORK WHOSE PARTICLE SIZE MAY BE DISCREETLY VARIED ENABLING THE WATER IN A FINALLY MOLDED PRODUCT TO BE QUICKLY AND READILY RELEASED WITH OR WITHOUT THE APPLICATION OF HEAT THERETO. IN ONE EMBODIMENT, CONTROLLED AMOUNTS OF SELECTED SURFACTANTS, WHETHER THEY ARE CONSIDERED TO BE EMULSIFIERS, SOLUBILIIZERS, DISPERSING AGENTS, WETTING AGENTS OR DETERGENTS, ARE ADDED TO THE RESIN/WATER MOLDING COMPOUND EMULSION AND UNDER CONTROLLED MIXING CONDITIONS THERE IS A REGULATED RELEASE OF WATER FROM THE WATER/POLYESTER MOLDING COMPOSITION AND EMULSION.

摘要： A PROCESS FOR THE FORMATION OF EXPANDABLE THERMOPLASTIC SYNTHETIC RESIN EMPLY VIBRATION TO ASSURE A UNIFORM ARTICLE CONSTRUCTION. THE PARTICULAR ARTICLE MOLD CAVITY IS LOADED WITH UNEXPANDED RESIN BEADS AND IS SIMULTANEOUSLY VIBRATED AND HEATED UNTIL THE BEADS HAVE BEEN

FULLY EXPANDED, THE PROCESS FURTHER ENABLES A USER TO CREATE LAMINATIONS WITHIN A MOLDED ARTICLE BY USING EXPANDABLE BEADS OF DIFFERENT DENSITIES OR OTHER SIMILAR MOLDABLE MATERIALS.
