    摘要： Copolymers of styrene or a-methylstyrene and at least one comonomer, containing crosslinked elastomer particles, can be light-stabilized by modifying the elastomer particles by copolymerization with a suitable derivative of a sterically hindered amine. The modification is preferably carried out by graft polymerization, the elastomer used preferably being polybutadiene.

    摘要： Blocked benzotriazoles of the formula I or II ##STR1## wherein x is 1 or 2, R.sup.1 in the case of x=1 and in the formula II is an acyl group of the formula --CO--R.sup.5, a sulfonyl group of the formula --SO.sub.2 --R.sup.6, a phosphoryl group of the formula --P(O).sub.r (R.sup.14)(R.sup.15), and in the case of x=2 is --CO-- or a diacyl group of the formula --CO--CO-- or --CO--R.sup.7 --CO--, and R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.14 and R.sup.15 have the meanings defined in claim 1, are crypto light stabilizers which can be activated by short-wave irradiation. Their use in coating materials is of interest in cases in which light stabilizers containing the free OH compounds have disadvantages with regard to their application.

    摘要： Compounds of the formula ##STR1## and their acid addition salts, wherein n is an integer from 1 to 4, R.sup.1 is hydrogen or CH.sub.3, each of R.sup.2 and R.sup.3 independently is hydrogen, C.sub.1 -C.sub.18 alkyl, C.sub.6 -C.sub.10 aryl or C.sub.7 -C.sub.9 aralkyl which is unsubsititued or substituted by chlorine or C.sub.1 -C.sub.4 alkyl, or R.sup.2 and R.sup.3 together with the carbon atom to which they are attached form a cycloalkane or alkylcycloalkane radical containing 5 to 20 carbon atoms or a polyalkylpiperidine radical, R.sup.4 is a monovalent radical as defined in claim 1, and R.sup.5 is a mono- to tetravalent radical as defined in claim 1. These compounds are valuable stabilizers for plastics. They are obtained by N-substitution of the compounds in which R.sup.4 and R.sup.5 are hydrogen.
