PROCESS FOR PRODUCING NONAQUEOUS LIQUID DISPERSION OF POLYMER PEROXIDE COPOLYMERS WITH VINYL COMPOUNDS

Abstract

Abstract Translated from French CONFORMEMENT A L'INVENTION, ON COPOLYMERISE UN PEROXYDE POLYMERE SPECIFIQUE AVEC DES MONOMERES VINYLIQUES EN PRESENCE D'UN LIQUIDE ORGANIQUE, CE QUI DONNE UNE SOLUTION DE COPOLYMERE COMPORTANT DES LIAISONS PEROXY. CETTE SOLUTION EST MELANGEE AVEC DES MONOMERES VINYLIQUES DIFFERENTS DE CEUX UTILISES DANS LA PREMIERE COPOLYMERISATION PRECITEE ET LE MELANGE RESULTANT EST SOUMIS A UNE COPOLYMERISATION SEQUENCEE. LA SOLUTION DE COPOLYMERE SEQUENCE OBTENUE EST MELANGEE AVEC UN LIQUIDE ORGANIQUE QUI EXERCE UNE ACTION SOLUBILISANTE SUR UN DES POLYMERES DES MONOMERES VINYLIQUES QUI SONT UTILISES DANS LA PREMIERE OU DANS LA SECONDE COPOLYMERISATION, CE QUI DONNE UNE DISPERSION LIQUIDE NON AQUEUSE. CES DISPERSION CONTIENT, A UNE CONCENTRATION ELEVEE, UN COPOLYMERE SEQUENCE. L'UNIFORMITE DE CETTE DISPERSION ET SA STABILITE SONT EXCELLENTES. IN ACCORDANCE WITH THE INVENTION, A SPECIFIC POLYMER PEROXIDE IS COPOLYMERIZED WITH VINYL MONOMERS IN THE PRESENCE OF AN ORGANIC LIQUID, WHICH GIVES A COPOLYMER SOLUTION CONTAINING PEROXY BONDS. THIS SOLUTION IS MIXED WITH VINYL MONOMERS DIFFERENT FROM THOSE USED IN THE ABOVE FIRST COPOLYMERIZATION AND THE RESULTING MIXTURE IS SUBJECT TO SEQUENCED COPOLYMERIZATION. THE COPOLYMER SEQUENCE SOLUTION OBTAINED IS MIXED WITH AN ORGANIC LIQUID WHICH EXERCISES A SOLUBILIZING ACTION ON ONE OF THE POLYMERS OF THE VINYL MONOMERS WHICH ARE USED IN THE FIRST OR IN THE SECOND COPOLYMERIZATION, WHICH GIVES A NON-AQUID DISPERSION. THESE DISPERSION CONTAINS, AT A HIGH CONCENTRATION, A COPOLYMER SEQUENCE. THE UNIFORMITY OF THIS DISPERSION AND ITS STABILITY ARE EXCELLENT.
