1996-1-1 · Poly(dimethyl siloxane) (PDMS) is an extremely versatile polymer. It is unique in that it has a silicon-oxygen backbone instead of a carbon backbone. Its properties are less temperature sensitive than other rubbers because of its lower T g. PDMS is used in catheter and drainage tubing, in insulation for pacemaker leads, and as a component in .
2008-12-1 · On the other hand, the crystal lattice of 2:1 layered silicates (or 2:1 phyllosilicates), consists of two-dimensional layers where a central octahedral sheet of alumina is fused to two external silica tetrahedra by the tip, so that the oxygen ions of the octahedral sheet also belong to the tetrahedral sheets, as shown in Fig. 1.The layer thickness is around 1 nm and the lateral dimensions may .
Description. Ethylene glycol ethers and glycol ether acetates are clear liquids with mild, pleasant odors. Due to the presence of both an ether and a hydroxyl group in the same molecule, these products are miscible in water, as well as most organic solvents, making this group of products ideal for use as resin solvents in the paint and coating industry.
2017-1-1 · Self-condensation into higher ether diols (e.g., diethylene glycol from ethylene glycol) which can be incorporated into the resin structure. The degree to which these effects contribute to the structure of the polyester is largely determined by the acidity of the mixture and the temperature reached in the reactor. 26.3.2.1.

Dimethyl Methylphosphonate. Dimethyl methylphosphonate (DMMP) is made by molecular rearrangement of trimethyl phosphite. It contains 25 wt % phosphorus (near the maximum possible for a phosphorus ester) and it is therefore highly efficient on a weight basis as a flame retardant. DMMP is a low viscosity colorless liquid bp 185°C.
The present invention relates to hot-melt adhesive compositions comprising in addition to 2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl-4-methylphenyl]acrylate as an antioxidant at least one carbodiimide compound.
