Polymers containing cyclic ether units joined through 2,6-diyl linkages. |
摘要 |
<p>This invention relates to polymers containing cyclic ether units joined through 2,6-diyl linkages. The polymers have a number average molecular weight of at least 1000 and contain at least 5% by weight of segments containing at least two consecutively recurring cyclic ether units, at least one of which is a tetrahydropyran 2,6-diyl unit. The remaining cyclic ether units in the segment are selected from tetrahydropyran 2,6-diyl units and tetrahydropyran 2,5-diyl units.</p><p>Preferably the polymer contains at least six cyclic ether units wherein at least 30% of the junctures between adjacent cyclic ether units have a threo configuration.</p><p>The polymer is useful as an adhesion promoter. Additionally, when the cyclic ether units are joined together in the above-described threo configuration, the polymers form stable complexes with organic and inorganic cations and are useful in phase transfer applications and as dispersing agents for inorganic particles in nonaqueous solvents.</p> |
