摘要:
The present invention provides a thermally expandable microsphere having a core-shell structure comprising: a shell including a thermoplastic polymer and a long-chain crosslinking agent having a weight-average molecular weight between cross-linking sites of more than about 500; and a core including a foaming agent. The thermally expandable microsphere of the present invention can have excellent foaming characteristics and an even (uniform) microsphere diameter.
