Claims
- 1. A composition containing hydrolysis protective agents which comprises
- (a) a synthetic polymer containing ester groups and/or carbonate groups and
- (b) a quantity of about 0.1 to 10% by weight, based on the weight of component (a), of a 2,3,2',3'-bismorpholine derivative corresponding to the formula ##STR12## wherein R.sub.1 and R.sub.2 may be identical or different and represent alkyl, alkenyl, cycloalkyl or aryl substituents,
- R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen, alkyl, alkenyl, cycloalkyl and/or aryl substituents, or a cycloalkylene or arylene substituent formed by linkage of R.sub.3 and R.sub.6 with the proviso that R.sub.4 and R.sub.5 are omitted in the case of arylene,
- and wherein the cycloalkyl or aryl groups of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 or R.sub.6 may optionally contain inert substituents comprising a member selected from the group consisting of C.sub.1 -C.sub.7 -alkyl, chlorine or bromine.
- 2. The composition of claim 1 wherein
- R.sub.1 and R.sub.2 represent a CH.sub.3 group, a C.sub.2 H.sub.5 group, a cyclohexyl group or a phenyl group and
- R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen or the groups R.sub.3 and R.sub.6 form a cyclohexane group while R.sub.4 and R.sub.5 represent hydrogen or a C.sub.1 to C.sub.7 -alkyl group.
- 3. The composition of claim 2 wherein R.sub.1 and R.sub.2 represent methyl or cyclohexyl.
- 4. The composition of claim 3 wherein R.sub.3 and R.sub.6 form a cyclohexane group and R.sub.4 and R.sub.5 represent hydrogen.
- 5. The composition of claim 3 wherein R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen.
- 6. The composition of claim 1 wherein R.sub.1 and R.sub.2 represent methyl and R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen.
- 7. The composition of claim 1 wherein said synthetic polymer is a polyurethane comprising the reaction product of a polyisocyanate and a polyol containing ester groups and/or carbonate groups.
- 8. The composition of claim 7 wherein
- R.sub.1 and R.sub.2 represent a CH.sub.3 group, a C.sub.2 H.sub.5 group, a cyclohexyl group or a phenyl group and
- R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen or the groups R.sub.3 and R.sub.6 form a cyclohexane group while R.sub.4 and R.sub.5 represent hydrogen or a C.sub.1 to C.sub.7 -alkyl group.
- 9. The composition of claim 8 wherein R.sub.1 and R.sub.2 represent methyl or cyclohexyl.
- 10. The composition of claim 9 wherein R.sub.3 and R.sub.6 form a cyclohexane group and R.sub.4 and R.sub.5 represent hydrogen.
- 11. The composition of claim 9 wherein R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen.
- 12. The composition of claim 7 wherein R.sub.1 and R.sub.2 represent methyl and R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent hydrogen.
