THREE-STAGE MOLDING GRAFT COPOLYMERS, WHICH CONTAIN THEM, WEATHER-RESISTANT, MATT AND THERMOPLASTIC WITH A HIGH COLD TENACITY.

摘要

THE PRESENT INVENTION REFERS TO GRAFT POLYMERIZATION, OBTAINABLE THROUGH (A) POLYMERIZATION FROM 10 TO 89% BY WEIGHT OF A MIXTURE COMPOSED ESSENTIALLY OR WELL FROM (A1) 70 TO 99.89% BY WEIGHT OF A REST C1 - C18 RENTAL OF ACRYLIC ACID, WHERE THE REST OF RENTAL CAN BE SIMPLY REPLACED BY A FENILE GROUP OR FENOXI GROUP, (A2) 0.1 UP TO 10% BY WEIGHT OF A POLYFUNCTIONAL MONOMER, (A3) 0 UP TO 29.89% WEIGHT OF ONE OF THE ETHYLENICALLY DIFFERENT NON-SATURATED MONOMERS OF (A1) AND (A2), COPOLYMERABLE WITH IT, WHICH DOESN'T CARRY ANY ACID GROUP, AND (A4) 0.01 UP TO 10% BY WEIGHT OF A COPOLYMERABLE MONOMER CONTAINING AT LEAST AN ACID GROUP OR (A5) 49.99 UP TO 99.99% BY WEIGHT OF AT LEAST ONE DIENO, (A6) 0 UP TO 50% BY WEIGHT OF A COPOLYMERIZABLE MONOMER THAT DOESN'T CARRY ANY ACID GROUP, AND (A7) 0.01 UP TO 10% BY WEIGHT OF A COPOLYMERIZABLE MONOMER CONTAINING AT LEAST ONE ACID GROUP IN THE PRESENCE OF 1 TO 80% BY WEIGHT OF A RETICULATED SILICONE RUBBER , AND (B) POLYMERIZATION FROM 10 TO 89% BY WEIGHT OF A COMPOSITE MIX ESSENTIALLY FROM (B1) 50 TO 99.99% BY WEIGHT OF A COMPOUND STYLING OF THE GENERAL FORMULA (I) WHERE R1 AND R2 INDEPENDENT ONE OTHER MEAN HYDROGEN, C1 - C8 - RENT OR FENILE SUBSTITUTED WITH C1 - C4 - RENT UP TO THREE TIMES AND / OR A REST C2 - C8 - RENT OF METHACRYLIC ACID OR ACRYLIC ACID, (B2) 0 UP TO 50% BY WEIGHT OF ONE MONOMER, CHOSEN FROM THE GROUP COMPOSED OF METACRILNITRIL, ACRILNITRIL, METACRILIC ACID, ACRYLIC ACID, ANHYDRID OF MALEINIC ACID, MALEINIMIDA N-SUITUIDA WITH C1 - C4 - ALKYL, STERVINIL ACID C2 (B3) 0.01 UP TO 20% BY WEIGHT OF A COPOLYMERIZABLE MONOMER CONTAINING AT LEAST ONE BASIC GROUP IN THE PRESENCE OF GRAFT POLYMERIZED (A).
