s*******n 发帖数: 452 | 8 What Goes Wrong With Cars, and When
By Larry Carley c2009
Owning and driving a car involves two things most motorists would rather
avoid: spending money on maintenance and spending money on repairs.
If you do not maintain your car (meaning regular oil changes, filter
replacements and keeping an eye on critical fluid levels), you will be faced
with major repairs much sooner than you should. Most people realize a car
is an investment, and to get the most out of your investment you have to
take car... 阅读全帖 |

拜托各位! |

c****n 发帖数: 134 | 37 people don't solve all the problems; rather, they leave the real challenge
behind.
1) For ATRP: several papers attempted preparing triblock copolymers as
Thermoplastic elastomers, but without decent properties (I would say results
are lousy).
2) It was claimed in a review "virtually all monomers are polymerized in
living XXXX polymerization". A critical review would add "but only a few are
truly living and in most cases the polydispersity is too large". |

c****n 发帖数: 134 | 38 my boss mentioned that Kaneka Company of Japan is commercializing ATRP.
the product may be an acrylic Thermoplastic Elastomer.
anybody to confirm? any other commercial activity? |
