| 제목 | Hydrolytic Stability and Anti-abrasive Property of Waterborne Polyurethane by Copolyester |
| 초록 | New type of polyester polyol with alkyl side groups, poly(2,4-diethyl-1,5-pentamethylene adipate) glycol (PDPAd) was synthesized and was used to improve the hydrolytic stability of waterborne polyurethanes. The results were favorably compared with poly(tetramethylene adipate) glycol (PTAd) based PU and copolymers of the two types of polyol in terms of mechanical, dynamic mechanical, and swell behavior of the dispersion cast films in addition to hydrolytic stability and anti-abrasion property. We prepared copolyester polyurethanes from PDPAd, PTAd, hexanediisocyanate(HDI), 4,4'-methylenebis cyclohexyl diisocyanate(H12MDI), 1,4-butanediol(1,4-BD) and triethylene tetramine(TETA) according to a prepolymer mixing process. The content of hard segments, combination of different polyols were the design variables to control the property response. Hydrolytic stability of copolyester polyurethanes were improved. Anti-abrasion was also improved with increasing hard segment content. |
