polyoxypropylene造句

例句与造句

1. P407 = poloxamer with a polyoxypropylene molecular mass of 4, 000 g / mol and a 70 % polyoxyethylene content ).
2. This aggregation is driven by the dehydration of the hydrophobic polyoxypropylene block that becomes progressively less soluble as the polymer concentration or temperature increases.
3. Eventually, a complete dehydration of the polyoxypropylene blocks and the collapse of the polyoxyethylene chains will lead to clouding and / or macroscopic phase separation.
4. Thus, the core of the aggregates is made from the insoluble blocks ( polyoxypropylene ) while the soluble portion ( polyoxyethylene ) forms the shell of the micelles.
5. The final geometry will depend on the entropy costs of stretching the blocks, which is directly related to their composition ( size and polyoxypropylene / polyoxyethylene ratio ).
6. It's difficult to find polyoxypropylene in a sentence. 用polyoxypropylene造句挺难的
7. For the generic term " poloxamer ", these copolymers are commonly named with the letter " P " ( for poloxamer ) followed by three digits : the first two digits x 100 give the approximate molecular mass of the polyoxypropylene core, and the last digit x 10 gives the percentage polyoxyethylene content ( e . g.
8. For the Pluronic and Synperonic tradenames, coding of these copolymers starts with a letter to define its physical form at room temperature ( L = liquid, P = paste, F = flake ( solid ) ) followed by two or three digits, The first digit ( two digits in a three-digit number ) in the numerical designation, multiplied by 300, indicates the approximate molecular weight of the hydrophobe; and the last digit x 10 gives the percentage polyoxyethylene content ( e . g ., L61 indicates a polyoxypropylene molecular mass of 1, 800 g / mol and a 10 % polyoxyethylene content ).
