POLYMER PARTICLE DISPERSIONS WITH DIVINYLARENE DIOXIDES

摘要

A toughener composition comprising a) 45 to 97 weight percent of a divinylarene dioxide; and b) 3 to 55 weight percent of a core shell rubber comprising a rubber particle core and a shell layer wherein said core shell rubber has a particle size of from 0.01μm to 0.50μm is disclosed. The toughener can be used in epoxy resin compositions for advanced composite, electronic, coating and structural adhesive applications.
