Dicing Tape
A reactive polymer is obtained by adding KarenzMOI™ to BA-EA-AA-HEA copolymer. An adhesive tape is then made by mixing this with penta-erythritol triacrylate and polymerization catalyst, and spreading this coating onto a polypropylene film. Semiconductor wafers placed on this tape do not come off during dicing, but when subjected to ultraviolet irradiation after dicing is completed, curing and contraction take place and the tape can be completely removed without any remnants being left on the wafers. This is due to the use of KarenzMOI™ as a constituent, allowing molecular design to be easily carried out and enhancing the yield of adhesive.

Emulsion Paint
Macromonomers can be obtained by the reaction between KarenzMOI™ and compounds which have both the hydrophobic and hydroxyl groups, such as PEG monononylphenyl ether. When emulsions containing polymers obtained by the polymerization of said macro-monomers are used in paints, the abrasion resistance and leveling greatly improve.
