The hydrosilylation cure of polyisobutene
Summary A liquid polyisobutene oligomer with unsaturated chain ends undergoes hydrosilylation with $ HMe_{2} $$ SiOMe_{2} $$ SiOMe_{2} $SiH or Si($ OMe_{2} $SiH)4 to give higher molecular weight polymers or elastomers. A major side reaction consumes SiH to give redistributed siloxane in the resultin...

| 520 | |a Summary A liquid polyisobutene oligomer with unsaturated chain ends undergoes hydrosilylation with $ HMe_{2} $$ SiOMe_{2} $$ SiOMe_{2} $SiH or Si($ OMe_{2} $SiH)4 to give higher molecular weight polymers or elastomers. A major side reaction consumes SiH to give redistributed siloxane in the resulting polymers and gaseous silanes and siloxanes as by-products. A second side reaction results in loss of reactivity in the oligomer due to a shift of the terminal double bond to an internal position. If the side reactions are taken into account, it is possible to forecast quantitatively molecular weight, gel point and modulus from the conversions of >SiH, >C=$ CH_{f2} $ and the chain entanglement concentration reported for polyisobutene in the literature. | ||

The hydrosilylation cure of polyisobutene |
| abstract |
Summary A liquid polyisobutene oligomer with unsaturated chain ends undergoes hydrosilylation with $ HMe_{2} $$ SiOMe_{2} $$ SiOMe_{2} $SiH or Si($ OMe_{2} $SiH)4 to give higher molecular weight polymers or elastomers. A major side reaction consumes SiH to give redistributed siloxane in the resulting polymers and gaseous silanes and siloxanes as by-products. A second side reaction results in loss of reactivity in the oligomer due to a shift of the terminal double bond to an internal position. If the side reactions are taken into account, it is possible to forecast quantitatively molecular weight, gel point and modulus from the conversions of >SiH, >C=$ CH_{f2} $ and the chain entanglement concentration reported for polyisobutene in the literature. © Springer-Verlag 1987 |
