标题:One-pot synthesis of nanoparticles and liquid polymer for rubber applications
发明人：WARREN SANDRA
权利人:BRIDGESTONE CORP
摘要:A method for performing a one-batch synthesis of a blend of nanoparticles and liquid polymer includes polymerizing a first monomer and optionally a second monomer in a hydrocarbon solvent to form the liquid polymer. The polymerization is terminated before completion with a quenching agent. Then a charge of polymerization initiator, and a mixture of multiple-vinyl aromatic monomer and mono-vinyl aromatic monomer are added. This causes further polymerization whereby nanoparticles are formed in situ having a core including the multiple-vinyl aromatic monomer, and a shell including the first monomer or the first monomer and the second monomer. Liquid polymer/nanoparticle blends resulting from the method and rubber compositions incorporating the blends are also disclosed.

摘要:A method for the solid-phase synthesis of peptides or proteins in high yield and high purity uses a solid support consisting of a functionalized polystyrene-grafted polymer substrate, the grafted polystyrene chains being substantially non-cross-linked and having a chain molecular weight, not including optional non-reactive substituents, of at least 200,000, preferably in the range of 600,000-1,200,000. Particularly suitable polymer substrates are substrates of a polyolefin such as polyethylene. The method is particularly well-suited to the compartmentalized synthesis of a multitude of peptides or proteins in a parallel and substantially simultaneous fashion. n Preferred embodiments of a solid support for performing the synthesis are prepared from thin polyethylene sheet or film which has been grafted with polystyrene chains in a radical-initiated process in which the polyethylene sheet or film is immersed in a solution of optionally substituted styrene monomer in an alcohol such as methanol, the volume percentage of styrene in the solution preferably being about 30% v/v, and subjected to gamma irradiation.

摘要:Synthesis of tungsten pentahalide compositions having low impurity profiles are disclosed. The specific impurity profile permits deposition of high purity tungsten-containing films using vapor deposition processes or other semiconductor manufacturing processes without introduction of performance-impacting contaminants.
