Abstract:
A polymeric acetal with the repeat structural unit (I) ##STR4## wherein R.sup.1 and R.sup.2 are, independently of one another, H, a branched or unbranched, saturated or unsaturated C.sub.1 -C.sub.12 -alkyl radical or a phenyl or naphthyl radical,R.sup.3 and R.sup.5 are, independently of one another, a branched or unbranched, substituted or unsubstituted C.sub.1 -C.sub.30 -alkylene or C.sub.2 -C.sub.30 -alkenylene radical, a phenylene radical or a naphthylene radical,R.sup.4 is a branched or unbranched C.sub.1 -C.sub.200 -alkylene or cycloalkylene radical, a C.sub.6 -C.sub.200 -arylene or alkylarylene radical, where these radicals may be substituted by heteroatoms such as F, Cl, Br or l or can be interrupted by heteroatoms such as oxygen, sulfur or nitrogen,X and Y are, independently of one another, either O or NR.sup.6, where R.sup.6 is either H or a branched or unbranched C.sub.1 -C.sub.30 -alkyl or cycloalkyl radical or a C.sub.6 -C.sub.50 -aryl or C.sub.7 -C.sub.50 -alkylaryl radical,n and m are numbers from 0 to 10, the sum of which is greater than 0, and if X.dbd.NR.sup.6, the number m is not 0 and if Y.dbd.NR.sup.6, the number n is not 0, andz is a number from 2 to 100.
