Solid polyethylene glycol in powder form with bimodal particle size distribution, its production and its use
摘要：
A solid polyethylene glycol with an average molecular mass of from 1500 to 40 000 in the form of a powder with a bimodal particle size distribution, with from 0 to 15% by weight of particles smaller than 100 micrometers, 10 to 90% by weight of particles between 100 and 200 micrometers, 0 to 25% by weight of particles between 200 and 300 micrometers, 10 to 90% by weight of particles between 300 and 1000 micrometers and 0 to 10% by weight of particles larger than 1000 micrometers is claimed.
