Patent Title: HIGHLY DURABLE POLYESTER POLYOL
Number/Link: US2017/0022143
Applicant/Assignee: Kuraray
Publication date: 26-jan-2017
“Gist”: PU from polyester polyol with bulky side groups
Why it is interesting: The invention is about polyester polyols prepared from a dibasic acid (e.g adipic acid) and a mixture of two diols: 3-methyl-1,5-pentanediol and cyclohexane-1,1-dimethanol. The diols are used in a molar ratio of about 1:1 (25-75 to 75-25 pref.). Polyurethanes prepared with these polyesters are said to be highly hydrolysis resistant in both acidic and basic environments.
