Acrylic acid derivatives of 2,2,6,6-tetramethylpiperidines
Abstract
Abstract NEW ACRYLIC ACID DERIVATIVES HAVING THE FORMULAE I AND II 2,2,6,6-TETRA(CH3-),4-R1,4-(R3-CH=C(-R2)-CO-X-)PIPERIDINE 1-(R3-CH=C(-R2)-CO-),2,2,6,6-TETRA(CH3-),4-R1, 4-(R3-CH=C(-R2)-CO-X-)PIPERIDINE (II) WHEREIN R1 REPRESENTS HYDROGEN ATOM OR CYANO GROUP; R2 AND R3 MAY BE THE SAME OR DIFFERENT AND EACH REPRESENTS HYDROGEN ATOM OR METHYL GROUP; AND X REPRESENTS IMINO GROUP OR OXYGEN ATOM. THEY ARE USEFUL AS A STABILIZER FOR THE DETERIORATION OF VARIOUS SYNTHETIC POLYMERS AND ALSO COPOLYMERIZED TO FORM NEW HIGHLY LIGHT-STABLE POLYMERIC COMPOUNDS. THE ACRYLIC ACID DERIVATIVES (I) AND (II) ARE PRODUCED BY REACTING A PIPERIDINE DERIVATIVE HAVING THE FORMULA 2,2,6,6-TETRA(CH3-),4-R1,4-(H-X-)PIPERIDINE (III) WHEREIN R1 AND X ARE AS DEFINED ABOVE WITH A REACTIVE DERIVATIVE OF AN UNSATURATED ALIPHATIC CARBOXYLIC ACID HAVING THE FORMULA R3-CH=C(-R2)-COOH WHEREIN R2 ND R3 ARE AS DEFINED ABOVE.
