摘要:
This invention relates to the use of an effective amount of a composition based on a palladium catalyst for preparing a polyaddition heat type curable polyorganosiloxane elastomer. It is also directed to a polyaddition heat type curable polyorganosiloxane elastomer.
摘要:
This invention relates to silicone compositions which can be crosslinked, preferably into elastomers, by hydrosilylation of at least one PolyOrganoSiloxane -A- carrying unsaturated bonds, using at least one polyorganohydrosiloxane -B- in the presence of carbene-based metal catalyst -C- as defined in claim 1 and which optionally comprise at least one inhibitor -D- of the hydrosilylation reaction.

This invention relates to a one part mixture based on a PGM catalyst, a PGM inhibitor thereof and a ligand, convenient for the catalysis of hydrosilylation reactions and to polyaddition-curable polyorganosiloxane compositions including such a mixture
摘要:
The invention provides methods, systems and apparatus, including computer program apparatus, implementing techniques for processing experimental data derived from a combinatorial library of materials. The techniques include providing an experiment protocol defining a program of actions to be carried out during a set of experiments and executing the program of actions. The protocol includes at least a first action linked to a library description of a combinatorial library. The library description includes data identifying a plurality of library positions corresponding to a plurality of members of the combinatorial library. Execution of the first action includes performing a method specified by the first action using the library description as an input.
