EMULSION POLYMER ADHESIVES USEFUL AS PRESSURE-SENSITIVE ADHESIVES WHILE MAINTAINING EXCELLENT BALANCE

摘要

PURPOSE: A multi-step emulsion polymer is provided to ensure high exfoliation, high temperature adhesion, and the balance of pressure-sensitive adhesives, and to be suitable for forming pressure-sensitive adhesives with high exfoliation and high temperature adhesion.;CONSTITUTION: A multi-step emulsion polymer comprises a first polymer 90-99.5 wt% and a reinforced polymer 0.5-10 wt% based on the total weight of the first polymer and reinforced polymer. The polymer is formed by at least one ethylenic unsaturated monomer and Tg is -20 °C or less and is polymerized in the presence of a chain transfer agent 3-12 mmol per monomer 1 kg.;COPYRIGHT KIPO 2010
