摘要： A PROCESS FOR PREPARATION OF COPOLYMERIZABLE COMPOSITIONS COMPRISING REACTING MALEIC ANHDRIDE WITH ONE OR MORE POLYHYDROXYLATED COMPOUNDS IN THE RATIO OF 1 MOLE MALEIC ANHDRIDE PER HYDROXYL GROUP OF THE RANGE OF Y LATED COMPOUNDS AT A TEMPERATURE WITHIN THE RANGE OF 50-100* C. UNTIL A HYDROXYL NUMBER OF 20 OR BELOW IS REACHED AND THEREAFTER ADDING AT A TEMPERATURE WITHIN ONE RANGE OF ROOM TEMPERATURE TO 100* C. OF AT LEAST ONE CROSS-LINKING VINYL MONOMER IN THE PRESENCE OF A POLYMERIZATION INHIBITOR.
