USE OF SULFUR AND SULFUR DONOR IN CROSSLINKAGE OF HIGHLY VISCOUS SELF-ADHESIVE HIGH TEMPERATURE MELT PRESSURE- SENSITIVE ADHESIVE COMPOSITION HAVING NON-THERMOPLASTIC ELASTOMER AS BASE

摘要

PROBLEM TO BE SOLVED: To provide a high temperature melt pressure-sensitive adhesive having a sulfur-containing non-thermoplastic elastomer as the base. SOLUTION: In a high temperature melt pressure-sensitive adhesive having one or more non-thermoplastic elastomers as the base, the high temperature melt pressure-sensitive adhesive contains at least 100 pts.wt. non-thermoplastic elastomer, 1-200 pts.wt. one or more tackifying resins, and sulfur and a sulfur donor, and contains 20 mmol to 8 mol free sulfur per kg of the non- thermoplastic elastomer used.
