Pressure-sensitive adhesives based on preferentially tackified immiscible elastomers |
摘要 |
A pressure sensitive adhesive of a mutually immiscible first elastomer (styrene-butadiene block copolymer) exhibiting a first glass transition temperature and a second elastomer (e.g., a styrene-isoprene-styrene block copolymer) exhibiting a second glass transition temperature greater than the first is tackified by a tackifying system comprising tackifier preferentially miscible with the second elastomer to provide a dynamic mechanical spectrum plot of tangent delta versus temperature in degreesC. showing two separate and distinct glass transition temperature peaks. The mixture exhibits excellent processability and ambient and low temperature adhesive properties.
