Abstract:
Reaction products obtained by mixing under anhydrous conditions
WHERE K IS 0 TO 20 AND A is methyl or vinyl and
WHERE M IS 0 TO 5 AND Y IS 1 OR 2 ARE ADHESION PROMOTERS WHICH ARE USEFUL IN PRIMER COMPOSITIONS. The primer compositions are organic solvent solutions with 50 to 99.9 weight percent organic solvent, with the balance being made up of 5 to 100 weight percent of the adhesion promoter, 0 to 50 weight percent of alkylsilicate and 0 to 50 weight percent of an organotitanate. An example of a primer composition would be a solution of 76.9 weight percent inhibited 1,1,1-trichloroethane with 23.1 weight percent of equal weight amounts of an adhesion promoter where A is vinyl, k is 3 and m has an average value of about 0.7, ethylpolysilicate and bis(acetylacetonyl)diisopropyltitanate. The primer compositions are useful in adhering room temperature vulcanizable silicone elastomers to substrates such as aluminum.

Abstract:
A METHOD FOR POLYMERIZING ORGANOSILICON COMPOUNDS IS DISCLOSED. CYCLIC ORGANOSILICON COMPOUNDS, SUCH AS ((CH3)2SIO)3, AND A CATALYST WHICH IS THE REACTION PRODUCT OF AN AROMATIC ORGANIC COMPOUND HAVING ANALIPHATIC CARBON-CARBON DOUBLE BOND AND TETRANITROMETHANE ARE MIXED. SILANOL CONTAINING ORGANOSILICON COMPOUNDS ARE POLYMERIZED BY MIXING THEM WITH THE DEFINED CATALYST.
