A TACKY AND PRESSURE SENSITIVE ADHESIVE COMPRISING ONE OR MORE ALIPHATIC ESTERS OF ACRYLIC, METHACRYLIC AND ACETIC ACID TOGETHER WITH ONE OR MORE OF GLYCIDYL ACRYLATE, GLYCIDYL METHACRYLATE OR GLYCIDYL ALLYL ETHER IS DISCLOSED. THE PROPORTIONS OF MONOMERIC INGREDIENTS ARE SELECTED TO GIVE A CALCULATED GLASS TRANSITION TEMPERATURE FROM ABOUT -20*C. TO ABOUT -55*C. THE MONOMERIC SYSTEM IS COPOLYMERIZED AT A TEMPERATURE NOT EXCEEDING ABOUT 100*C. IN ORDER TO KEEP THE GLYCIDYL COMPOUNDS INTACT DURING POLYMERIZATION. |
