The coupling agent can have the structure I: wherein Z is an amine; R1-R10 are each, independent of one another, H, an organic functional group or a terminal alkene, wherein at least one terminal alkene is on each benzene ring; m is an integer from 1 to 8.
摘要:
A polymer containing a carboxyl group, a preparation method and an application thereof, a supported catalyst and a preparation method thereof and preparation methods of penem antibiotic intermediate are disclosed. The polymer has high rigidity and hardness, thus the mechanical properties of the polymer is effectively improved. Meanwhile, in the polymer, the carboxyl group is used as a main functional group, and is used as a carrier to prepare, by means of a coordination reaction between the carboxyl group and a heavy metal, a supported metal catalyst which has better connection stability between the metal and the polymer. The above two factors can improve the stability of the supported metal catalyst, such that the catalyst can be recycled without losing the catalytic activity. Meanwhile, loss of a heavy metal active ingredient and production cost can be reduced.

Amino-containing polymeric materials and methods of making these materials are provided. More specifically, the amino-containing polymeric materials are prepared by treating a precursor polymeric material with an amine compound. The precursor polymeric materials are formed from a polymerizable composition that contains a rigid and contorted divinyl crosslinker. The amino-containing polymeric materials can be used as anion exchange resins.

A polysulfide material having reactive vinyl end groups and a method of making a vinyl end-capped polysulfide material are described. The vinyl end-capped polysulfide material has potential applications as a sealant, an adhesive, a coating, a caulking, or the like. In a specific example, the polysulfide material may be used as a precursor material for a sealant resin in the manufacturing of an integral fuel tank of an aircraft. An example method for making polysulfide materials includes contacting a vinyl-functionalized aryl halide and/or a vinyl-functionalized heteroaryl halide with dithiols and/or trithiols in the presence of an organic solvent.

Disclosed herein are photopolymerizable compositions and formulations that comprise photochromic dyes, photochromic blue light blocking dyes, permanent dyes, permanent blue blocking dyes, and/or their combinations. In some variations, these formulations are suited for example, for sandwiching between lens blanks to form semi-finished lens assemblies to form a tinted lens useful in sunglasses. The formulations are also suitable for correcting optical aberrations, and may provide a photochromic effect when exposed to sunlight.
