摘要:
The invention describes novel compound of the formula (I) ,wherein the general symbols are as defined in claim 1, as stabilizers for protecting organic materials, in particular synthetic polymers, against oxidative, thermal, dynamic, light-induced and/or ozone-induced degradation.
摘要:
Compounds of the formula (I) wherein R1 is C1-C18alkyl, C5-C12-cycloalkyl, phenyl, benzyl, or allyl; n is 1 or 2; if n is 1, R2 is C4-C18alkyl, C5-C12cycloalkyl, aryl or heteroaryl, benzyl, allyl, (CH2),mCOOR3, or is (CH2)mCN; if n is 2, R2 is -S-(CH2)p-S or -S-(CH2)2-[O-(CH2)2]m-S R3 is C1-C18alkyl, benzyl, allyl; m is 1 or 2; and p is a number from 2 to 12; are suitable as a stabiliser for an elastomer to prevent oxidative, thermal, dynamic, light-induced and/or ozoneinduced degradation. They are also suitable as stabilizers for elastomers to prevent contact discoloration of substrates coming into contact with elastomers.
摘要:
Elastomers which have excellent stability to prevent oxidative, thermal, dynamic, light-induced and/or ozone-induced degradation comprise, as stabilizers, at least one compound of the formula (I): [R-S(=O)m-CH2-CH(OH)-CH2]n-N(R1)2-n-R2, in which R is C¿4?-C20alkyl, hydroxyl-substituted C4-C20alkyl; phenyl, benzyl, α-methylbenzyl, α,α-dimethylbenzyl, cyclohexyl or -(CH2)qCOOR?3¿, and, if m is 0, R may additionally be (a); and, if n is 1 and R4 is hydrogen, R may additionally be R?2-R1N-CH¿2-CH(OH)-CH2-S(=O)m-(CH2)x- or R?2-R1N-CH¿2-CH(OH)-CH2-S(=O)m-CH2-CH2-(O-CH2-CH2)y-, R1 is hydrogen, cyclohexyl or C¿3?-C12 alkyl, R?2¿ is (b), R3 is C1-C18alkyl, R4 is hydrogen or -CH¿2?-CH(OH)-CH2-S(=O)m-R, X is C1-C8alkyl, Y is C1-C8alkyl, m is 0 or 1, n is 1 or 2, q is 1 or 2, x is from 2 to 6, and y is 1 or 2. The compounds of the formula (I) are also suitable as stabilizers for elastomers to prevent contact discoloration of substrates coming into contact with elastomers.
