Abstract:
A siloxane polymer is made by providing a first compound having the chemical formula SiR1aR24-a where a is from 1 to 3, R1 is a reactive group, and R2 is an alkyl group or an aryl group, and providing a second compound having the chemical formula SiR3bR4cR54-(b+c) where R3 is a cross-linking functional group, R4 is a reactive group, and R5 is an alkyl or aryl group, and where b=1 to 2, and c=1 to (4−b). The first and second compounds are polymerized together to form a siloxane polymer. The siloxane polymer can be then used in a final composition where the siloxane polymer comprises from 5 to 100% by weight, and filler (e.g. microparticles, nanoparticles, nanowires, etc.) comprises from zero to 95% by weight. The siloxane polymer composition is useful in a variety of areas such as an adhesive, e.g. as a die attach adhesive in semiconductor (e.g. LED) packaging applications, encapsulants, optical coatings, protective coatings, and other applications.
