摘要: POWDERED COATING AGENT FOR USE IN THE ELECTROSTATIC SPRAYED POWDER PROCESS CONSISTING OF MIXTURES OF (A) COPOLYMERS (B) BIS- OR TRIS-OXAZOLINES AND OPTIONALLY (C) AUXILIARY AGENTS SUCH AS PIGMENTS AND FLOWING AGENTS. THE COPOLYMER CONTAINS POLYMERISED UNITS OF 25-60% STYRENE OR DERIVATIVES THEREOF OR (METH)ACRYLONITRILE; 30-65% BY WEIGHT OF ACRYLIC OR METHACRYLIC ESTERS AND 5-20% BY WEIGHT OF A,B-UNSATURATED CARBOXYLIC ACIDS. 5 TO 25 PARTS BY WEIGHT OF BIS- OR TRISOXAZOLINES ARE EMPLOYED FOR 95 TO 75 PARTS BY WEIGHT OF COPOLYMER.

摘要: MASKED OXYCARBONYLIXOCANATES ARE PREPARED BY REACTING ARYL OXYCARBONYLISOCYANATES WITH A COMPOUND CONTAINING AT LEAST TWO HYDROXYL GROUPS. WHEN NCO AND OH ARE PRESENT IN EQUIVALENT AMOUNTS, THE COMPOUNDS ARE SUITABLE AS REACTANTS WITH POLYMERS CONTAINING HYDROXYL GROUPS OF THE PRODUCTION OF, FOR EXAMPLE, LACQUERS. WHEN THE REACTION IS CARRIED OUT SUCH THAT OH GROUPS ARE PRESENT IN EXCESS OF THAT REQUIRED TO REACT WITH THE AVAILABLE -NCO, THE COMPOUNDS, WHICH ARE SELF CROSS-LINKING, ARE SUITABLE FOR THE PRODUCTION OF, FOR EXAMPLE, CROSS-LINKED SYNTHETIC RESINS.
