Title:
PHOTOCROSSLINKABLE LIQUID CRYSTALLINE POLYMER
Document Type and Number:
WIPO Patent Application WO/2018/096725
Kind Code:
A1
Abstract:
Provided is a novel liquid crystalline polymer with low tackiness that is produced by separating forming and curing (crosslinking). A photocrosslinkable liquid crystalline polymer including a site that is cured by photocrosslinking, wherein the tack value that is measured when the following test is performed is 0.3kg or less: (1) two test specimens 15-20mm wide and 100mm long are prepared; (2) one test specimen is adhered to a surface of a flat plate made from aluminum, while the other test specimen is adhered to a circumferential surface of a disc (50mm diameter, 14mm thick) made from aluminum; (3) the circumferential surface of the disc is pressed toward the surface of the flat plate with a load of 100g to adhere the two test specimens to one another; (4) the disc is pulled up at a speed of 3000mm/second, and the force when the disc separates from the flat plate is read as the tack value.
