1 Polyhexamethylene adipate diol and Polyurethane aquocmulsion based on the polyester are prepared.

2 The diol chain - extension agent is an important factor influencing the physical performance of TPU.

3 Vicinal diol can be effectively translated into azelaic acid and the corresponding dicarboxylic acid monomethyl ester.

4 Polyether diol mainly adopts polytetramethylene ether glycol ( PTMEG ).

5 Two 7-membered ring derivatives of S-(-)-2,2'- binaphthyl - diol, were synthesized.

6 4,5 - tetramethyl - 2 - cyclopentene - 1 - ol; 1,2 - diphenyl - 2 - hydroxy - 3 - butine - 1 - one; 3,4 - diphenyl - 1,5 - hexadiine - 3,4 - diol and 3, ...

7 The moisture cured polyurethane was synthesized with mixing polyether diol, toluene diisocyanate (TDI) as main raw materials, epoxy resin and hydroxy acrylic resin as modifiers.

8 A process for producing an alkenyl alcohol from a diol is disclosed.

9 cyclopentene - 1 - ol; 1,2 - diphenyl - 2 - hydroxy - 3 - butine - 1 - one; 3,4 - diphenyl - 1,5 - hexadiine - 3,4 - diol and 3,[]4 - diphenyl - 3 - cyclopentene - 1 - one.

10 No clear spherulitic morphology was observed in polarizing optical micrograph of PHB - diol.

11 The water - borne polyurethane was based on polyester diol and toluene diisocyanate etc.

12 Polyurethane hot - melt adhesive was prepared which polyester low molecular weight diol chain - extender, isocyanate and other.

13 The synthesis of oxyethylene oxypropylene copolyethers used for quenchant was studied by using anionic ring opening polymerization, diol or triol as the starting agent and KOH as the catalyst.
