PROCEDURE FOR THE PREPARATION OF CAST RESINS BASED ON METACRYLIC ACID ESTERS LOADED WITH ALUMINUM HYDROXIDE.

摘要

The present invention describes ester-based melt resins of methacrylic acid with a high fraction of aluminum hydroxide or aluminum oxide hydrate as filler. IN ACCORDANCE WITH THE INVENTION, THE FUSING RESINS CONTAIN A MIXTURE OF AT LEAST ONE ORGANOSILIC COMPOUND WITH FUNCTIONAL GROUPS, ONE SILICON ACID ESTER AND ONE METALLIC ACID COMPOSITE OF THE METALS OF THE PERIODIC PERIODIC SYSTEM . THE FUNCTIONAL GROUP OF THE ORGANOSILIC COMPOUND IS ETHYLENICALLY UNSATURATED AND INSTEAD OF DIRECTLY OR OVER THE ALKYLENE GROUPS, IT IS UNITED WITH THE SILICON ATOM. THE ADDITION OF THIS MIXTURE TO THE KNOWN MELTING RESINS PRODUCES THROUGH A DECREASE IN VISCOSITY A DESIRABLE IMPROVEMENT OF RESIN PROCESSING PROPERTIES. THE PLASTIC OBJECTS AND THE MOLDING BODIES PREPARED FROM THESE RESINS ARE CHARACTERIZED BY SIGNIFICANTLY IMPROVED USE QUALITIES.
