PROCESS FOR PREPARING A NEW RESIN FROM A PENTAGONAL CYCLIC COMPOUND HAVING A PAIR OF DOUBLE CONJUGATED LINKS AND / OR A CORRESPONDING DIELS-ALDER ADDITION PRODUCT, PROCESS FOR HYDROGENATING SUCH RESIN AND RESIN COMPOSITION CONTAINING THE RESIN HYDROGENATED

摘要

The invention relates to a process for producing a novel resin which consists in the copolymerization of a PENTAGONAL CYCLIC COMPOUND (COMPOSANTA) HAVING A PAIR OF DOUBLE CONJUGATED LINKS OF THE GENERAL FORMULA: BR/ (CF DRAWING IN BOPI) BR/ OR R REPRESENTS AN ALKYL RADICAL COMPRISING 1 TO 3 ATOMES OF CARBON, M AND N ARE 0 OR AT WHOLE NUMBERS AT LEAST 1 AND MN6, AND A DIELS-ALDER ADDITION PRODUCT CORRESPONDING, WITH A CODIMER (COMPONENT B) OF THIS PENTAGONAL CYCLIC COMPOUND AND 1,3-BUTADIENE, BY HEATING A MIXTURE OF 20 TO 90PARTIES BY WEIGHT OF THE COMPOSANTA AND FROM 80 TO 10 PARTS BY WEIGHT OF THE COMPONENT BA AT A TEMPERATURE OF 200 TO 350C; A METHOD FOR HYDROGENATING THIS NEW RESIN AND OBTAINING A NEW HYDROGENATED RESIN AS WELL AS RESIN COMPOSITIONS CONTAINING THE HYDROGENATED RESIN ARE ALSO DESCRIBED. / P
