HOMOGEN BLANDNING VESENTLIGEN BESTAENDE AV EN SAMPOLYETERESTER OCH ETT POLYMERT MJUKNINGSMEDEL, VILKET UTGORES AV EN POLYETERESTER ELLER EN SAMPOLYETERESTER |
摘要 |
A substantially uniform blend of (A) at least one copolyetherester having a melting point of at least 120 DEG C. which is prepared from a dicarboxylic acid, a low molecular weight diol and poly(tetramethylene oxide) glycol and (B) at least one polyetherester, which may be a copolymer. If a polyetherester is to be utilized it is prepared from poly(tetramethylene oxide) glycol and a dicarboxylic acid. If a polyetherester copolymer is to be utilized it is prepared from a dicarboxylic acid, a low molecular weight diol and poly(tetramethylene oxide) glycol. In any event, component (B) must be noncrystalline above 0 DEG C. and have an inherent viscosity above about 0.3. |
