摘要:
Compounds possessing both a hindered amine moiety, such as a derivative of 2,2,6,6-tetramethylpiperidine, and a nitrone moiety are valuable stabilizers for protecting polymer compositions against the deleterious effects of actinic light and from the adverse effects of high temperature polymer processing environments. Additionally, the instant compounds present the opportunity for grafting onto preformed polymer backbones.

摘要:
A process for preparing a 1-deoxynojirimycin of the formula ##STR1## in which R is hydrogen, optionally substituted alkyl or aralkyl, which comprises converting D-glucose to an aminosorbitol ##STR2## protecting the amino group of the aminosorbitol with an alkalinically detachable group to form the protected compound of the formula ##STR3## in which X is an alkalinically detachable protective group, microbiologically oxidizing the protected compound to an oxidation product of the formula ##STR4## alkalinically splitting off the protective group X to form an aminosorbose of the formula ##STR5## and reducing the aminosorbose.
摘要:
N-(.beta.-aminoethyl)-3-hydroxy-1,1,6,6-tetramethyl-piperidine and certain of its N- and O-substituted derivatives are useful as light stabilizers for polymeric materials, particularly for thermoplastic polymers and automotive finishes. Preferred compounds include the N-, O-diacyl derivatives.
摘要:
The invention provides compounds of formula ##STR1## wherein R.sub.1 and R.sub.2 are alkyl, R.sub.3 is hydrogen, alkyl, alkenyl, phenylalkyl or a group --(CH.sub.2 --CH.sub.2 --O).sub.n --R.sub.4 in which n is 1 to 3 and R.sub.4 is hydrogen or an acid residue, and the ring A is unsubstituted or substituted, with the proviso that when R.sub.3 is methyl the ring A is substituted.
