| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF NEW STATISTICAL COPOLYMERS OF VINYL-PIRROLIDONE. |
| abstract | PROCEDURE FOR THE PREPARATION OF NEW STATISTICAL COPOLYMERS OF VINYLPYRROLIDONE. CONSISTENT OF SUBMITTING TO A MASS POLYMERIZATION REACTION TO A MIXTURE FORMED BY: I) 10 TO 25% BY MOLS OF VINYLPYRROLIDONE; II) 30 TO 67.5% BY MOLES OF METHYL METHACRYLATE; E III) 7.5 TO 45% IN MOLES OF N- O OF ISO-BUTYL METHACRYLATE, TO OBTAIN A COPOLYMER WHOSE GLASS TRANSITION TEMPERATURE IS 85 TO 100 JC, AND WHOSE WATER ABSORPTION CAPACITY IS 2 TO 6% OF ITS WEIGHT. BEING THE MOLAR PROPORTION OF METHYL GROUPS IN THE ESTER PART, REFERRED TO THE SUM OF C 1 TO 8 ALKYL METHACRYLATE AND CYCLOALKYL, NOT HIGHER THAN 80% IN MOLES. IT IS USED IN THE MANUFACTURE OF IRIS LENS, CONTACT LENS AND CONTACT CAPSULES. |
