Abstract:
A hydrosilylation crosslinkable mixture comprising:a) at least one polysiloxane which has at least two olefinically or acetylenically unsaturated multiple bonds, b) at least one polyhydrogensiloxane which has at least two hydrogen atoms bound directly to a silicon atom, c) at least one substance which catalyzes hydrosilylation, d) at least one compound of the formula: R1nP(OR)3âˆ’nâ€ƒâ€ƒ(I) â€ƒwhere the subscript n is an integer ranging from 0 to 3, R and R1 are independently selected from the group consisting of where Râ€³ is selected from the group consisting of: H, CRâ€²â€³3, SiRâ€²â€³3, Halogen, ORâ€²â€³ and (CR42)mP(OR1)1R2âˆ’1 where the subscript l is an integer ranging from 0 to 2, the subscript m is an integer ranging from 1 to 10, where R4 is selected from the group consisting of H, CRâ€²â€³3, SiRâ€²â€³3, Halogen, and ORâ€²â€³ where at least one radical Râ€³ must be different from H and when n=0, at least one of the radicals Râ€³ is SiRâ€²â€³3, and Râ€²â€³ is selected from the group consisting of: i) saturated or unsaturated C1-C30 alkyl radicals, ii) saturated or unsaturated C1-C30 alkyl radicals, iii) saturated or unsaturated C7-C31 arylalkyl radicals and iv) saturated or unsaturated C7-C31 arylalkyl radicals bearing carboxylic acid derivative functional groups; where components c) and d) may be present as the reaction products thereof.
