Methyl Hydrogen Siloxanes. â¢ Possible applications include precursors to polyorganosiloxanes, cross-linking agents and chain extenders. â¢ Both silicone hydride homopolymers and dimethyl-copolymers are used to prepare polyorganosiloxanes; short chain. SiH-terminated fluids find applications as chain extenders and ABAin co-polymer manufacture. â¢ Hydrosilylation, the addition of a silicone hydride moiety across an unsaturated linkage, catalyzed by transition metal. complexes of rhodium or platinum, is commonly applied to the preparation of organofunctional siloxanes. Condensation cure chemistry is also widely used for preparation of crosslinked polymer matrices.
DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid. Although DNA and RNA both carry genetic information, there are quite a few differences between them. This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences.lthough DNA and RNA both carry genetic information, there are quite a few differences between them.

A gene carries the information required to make a particular kind of protein. 2. How does RNA differ from DNA? The sugar in RNA is ribose, instead of deoxyribose, the base uracil (U) is present in place of thymine (T), and RNA molecules are usually single-stranded and shorter than DNA molecules. D.1 D.2
