【摘要】 <正>高分子共混物 PAA/PEO 是一聚电解质体系,大量文献研究表明,在此体系中,PAA 侧链上的羧基和 PEO 主链中的醚氧基可以形成氢键作用,进而产生络合。PAA 以三种形态存在：(1)与 PEO 络合的形式,(2)二聚体的形式,(3)自由游离的形式。更多还原

【Abstract】 The hydrogen-bonded complex for PAA/PEO system has been intensively investigated by many researchers.It was shown that interpolymer hydrogen bonding occurs between the carboxyl proton -donor of PAA and the ether oxygen of PEO.There are three hydrogen bonding forms for carboxyl group of PAA,namely:(1)the complex form,interpolymer hydrogen bonding between PEO molecules;(2)the dimeric form,intrapolymer hydrogen bonding within PAA molecules;and (3)the free form,no particular form of hydrogen bonding.更多还原
