Abstract (en)

[origin: DE19757221A1] A vulcanizable mixture contains: (a) polysiloxane(s) (I) with at least two olefinically or acetylenic multiple bonds; (b) polyhydrosiloxane(s) (II) with at least two hydrogen (H) atoms bound directly to silicon (Si); (c) hydrosilylation catalyst(s) (III) (d) (het)aryl- and/or (het)aryloxyphosphine(s) (IV) or their reaction products with (III); and (e) optionally other ancillaries. (IV) has the structure: R<1>nP(OR)3-n (IV) R, R<1> = optionally substituted phenyl, pyrid-4-yl, fur-3-yl and/or thien-3-yl groups of the formulae (a) - (b): R'' = H, -CR'''3, -SiR'''3, halogen, -OR' and/or -(CR<4>2)m-P(OR<1>)lR2-l; l = 0-2; m = 1-10; R<4> = H, -CR'3, SiR'3, halogen, -OR' and/or SiR'; At least one R'' is not H. If n = 0, at least one R'' is SiR'3. R''' = an (un)saturated 1-30 C alkyl, aryl, 7-31C arylalkyl and/or 7-31C alkylaryl derivative, optionally with a functional group, e.g. carboxylic acid derivative Independent claims are also included for (a) silicone rubber obtained by vulcanizing the mixture at 40-250 deg C; and (b) the production of the mixture.
