    摘要: A process for preparing polyacetals by copolymerization of glyoxylic esters with other copolymerizable monomers in the presence of anionic or cationic polymerization initiators, with or without the introduction of stable end groups and with or without hydrolysis of the copolymerized units of glyoxylic ester present in the copolymer comprises using as monomers cyclic formals derived from diols, homopolymers of formaldehyde, trioxepane or mixtures thereof, although up to 50% by weight of this group of monomers may be replaced by other customary copolymerizable monomers, and the poly(acetal-carboxylate)s thus obtainable are useful as additives in reduced-phosphate and phosphate-free detergents and cleaners, as water treatment agents and as dispersants for finely divided substances.
