【Abstract】Theresearch progress of SIS-based hot melt pressure sensitive adhesive and polyurethane
hot melt pressure sensitive adhesive at home and abroad was reviewed in this
study. The advantages and disadvantages, modification methods (such as
polymerization modification, physical blending modification, chemical
modification), and research and application fields (such as metal bonding,
logistics labels, building waterproofing materials, and medical adhesives) of
both were elaborated, and the future development directions of SIS-based hot
melt pressure sensitive adhesive and polyurethane hot melt pressure sensitive
adhesive were also discussed.【Keywords】modified SIS; polyurethane; hot melt pressure sensitiveadhesive
Research progressof polyimide-based high-temperature resistant adhesive
【Abstract】Polyimide adhesive has outstanding high-temperature
resistance, dimensional stability, physical and chemical stability, dielectric
properties, and bonding properties, making it a type of adhesive with excellent
comprehensive performance, and therefore receiving increasing attention. In this
paper, the research progress of classic (thermoplastic, thermosetting)
polyimide adhesive, polyimide adhesive with molecular structure modification (molecular
main chain structure modification, end group structure modification), and blend
modified polyimide adhesive from the perspective of molecular structure was mainly
reviewed, and the future development trend of polyimide adhesive was
prospected.【Keywords】polyimide; adhesive; molecular structure
