Abstract
Core/shell particles comprising a core comprising an elastomer having a TG value of <0° C., onto which a shell of a crosslinked copolymer is grafted, where the proportion of the crosslinking component in the copolymer of the shell is from 5 to 90% by weight, based on the total amount of the comonomers of the shell copolymer, are suitable as toughening agents for epoxy resins, with which they have good compatibility.
Claims9
Core/shell particles comprising a core comprising an elastomer having a TG value of <0° C. onto which a shell of a crosslinked copolymer is grafted, where the proportion of the crosslinking component in the copolymer of the shell is from 6 to 60% by weight, based on the total amount of the comonomers in the shell copolymer.
