标 题:Catalysts and synthesis of high molecular weight amorphous polyolefins and recovery thereof
发明人:SEEGER HORST K; HOLLIDAY ROBERT E
权利人:EASTMAN CHEM CO
摘要:A process for the production of amorphous polyolefins is disclosed. The process entails contacting the olefin monomer, in an unreactive hydrocarbon solvent, with a catalyst in a recirculated, stirred reactor thereby producing amorphous polyolefin. The reactor is capable of recirculating contents that are very viscous.

标题 :System and method for manufacturing water-based hydrophobic aerogels and aerogel composites
发明人:SACHITHANADAM MAHESH; KHORASGANI SOGHRATI ELMIRA; NATARAJAN GAYATHRI
权利人:KROSSLINKER PTE LTD
摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.
