2. Polyisoprene - Wikipedia

   en.wikipedia.org/wiki/Polyisoprene

   Coordinative chain polymerization: With Ziegler–Natta catalyst TiCl 4 /Al(i-C 4 H 9) 3, a more pure cis-1,4-polyisoprene similar to natural rubber is formed. With Ziegler–Natta catalyst VCl 3 /Al(i-C 4 H 9) 3, trans-dominant polyisoprene is formed. [4] 1,2 and 3,4 dominant polyisoprene is produced MoO 2 Cl 2 catalyst supported by phosphorus ...

   Some are intended for ease of use and service, others are better for higher system pressures or control of leakage. The most common method, in general, is to provide in each component a female-threaded port, on each hose or tube a female-threaded captive nut, and use a separate adapter fitting with matching male threads to connect the two.

   A3M = Audio 3-pin male connector. The terms plug, pin, and prong are also often used for "male" connectors, and receptacle, socket, and slot are used for "female" connectors. In many cases these terms are more common than male and female, especially in documentation intended for the non-specialist. These nearly synonymous terms can cause a fair ...

8. Polysulfone - Wikipedia

   en.wikipedia.org/wiki/Polysulfone

   Bis(4-fluorophenyl)sulfone can be used in place of bis(4-chlorophenyl)sulfone. The difluoride is more reactive than the dichloride but more expensive. Through chain terminators (e.g. methyl chloride), the chain length can be controlled for melt-processing. The diphenol is typically bisphenol-A or 1,4-dihydroxybenzene. Such step polymerizations ...
