Title:
ブルームする傾向が低下した熱可塑性ポリウレタン
Document Type and Number:
Japanese Patent JP5684227
Kind Code:
B2
Abstract:
The present invention relates to a thermoplastic polyurethane (TPU) which is comprised of the reaction product of (1) a hydroxyl terminated polyester intermediate, (2) a polyisocyanate, and (3) a glycol chain extender; wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from 1,3-propylene glycol and a dicarboxylic acid; wherein the hydroxyl terminated polyester intermediate has a number average molecular weight which is within the range of 500 to 10,000 Daltons; and wherein the thermoplastic polyurethane includes hard segments that are the reaction product of the polyisocyanate and the glycol chain extender, wherein
- the dicarboxylic acid is of the formula: HOOC(CH 2 ) n COOH, wherein n represents an integer within the range of 2 to 10, and
- the glycol chain extender is selected from the group consisting of ethylene glycol, propylene glycol, 1,4-butane glycol, 1,5-pentane diol, 1,6-hexane diol, and hydroquinone bis (2-hydroxyethyl) ether. The TPU has a reduced tendency to bloom.
