Title:
CROSSLINKABLE BLOCK COPOLYMER AND COATING AGENT
Document Type and Number:
WIPO Patent Application WO/2020/149385
Kind Code:
A1
Abstract:
The present invention provides: a crosslinkable block copolymer that makes it possible to form a tough, tackless coating film; and a coating agent that uses the crosslinkable block copolymer. This crosslinkable block copolymer is characterized by including a polymer block B and a polymer block A that is bonded to both ends of polymer block B and contains a crosslinkable monomer unit. The crosslinkable block copolymer is also characterized in that, after crosslinking, when the non-linear least squares method is used to perform a two-component relaxation curve fitting on a decay curve that is obtained by applying the solid echo technique to 1H pulse NMR (20 MHz) at 40°C, the shorter spin-spin relaxation time T2(1) is 18–35 μsec, and the component ratio A1 of the relaxation curve that includes said spin-spin relaxation time T2(1) is 40%–70%.
