IPC: C08F210/12
Filed: 1988-12-08
Abstract: A substantially gel free C₄ to C₇ isoolefin homopolymer 
rubber, butyl copolymer rubber, halogenated butyl rubber (e.g., 
chlorinated or brominated), or mixtures thereof, comprising a 
molecular weight distribution such that the ratio of the moments of 
said molecular weight distribution, Mz/Mw, is equal to or exceeds 2.0, 
and that portion of said molecular weight distribution which is equal 
to and greater than 4 times the peak molecular weight, Mp, comprises 
greater than 8 percent of the total polymer species, and Mp is greater 
than about 250,000 and wherein said polymer species of molecular 
weight less than Mp are substantially branch free. Various means are 
disclosed for effecting the molecular weight distribution including 
blending of homopolymers and/or copolymers of appropriate molecular 
weight and molecular weight distribution and direct polymerization 
using a functional reagent to introduce branching. The rubber 
compositions are particularly useful in applications in which butyl or 
halogenated butyl rubber is used and where it is desired to obtain 
high green strength in combination with an increased rate of stress 
relaxation. Such polymers are particularly well suited for use in tire 
innerliner compositions.

Patent EP-0352721-A3 (EP)
IPC: C25D5/04
Filed: 1989-07-25
Abstract: Bei konventionellen Galvanisierverfahren wird das 
Substrat, z.B. eine mit einem halbleitenden Material 
beschichtete Glasplatte (1), in einem bewegten Metallsalzbad (2) 
metallisiert, z.B. vernickelt, wobei die Glasplatte als 
Kathode und eine Metallelektrode (3) als Anode geschaltet 
ist. Die Glasplatte wird langsam an der Metallanode 
vorbeigezogen  
     Das Problem liegt darin, schwierig zu galvanisierende 
Substratmaterialien, wie z.B. ITO (Indium-Tin Oxide), 
mit einer genügend haftfesten Metallschicht (z.B. 
Nickel) zu versehen.  
     Diese Problem wird dadurch gelöst, daß in das für die 
Metallisierung verwendete, Tenside enthaltende Nickelbad (5) 
von unten soviel Luft eingeblasen wird, daß sich an der 
Badoberfläche eine beständige Schaumschicht (8) bildet. In 
diese Schaumschicht taucht die Nickelanode (6) ein, an der 
die zu vernickelnde ITO-Glasplatte (1) langsam vorbeigezogen 
wird.  
     Damit wird eine sehr haftfeste Nickelschicht 
gleichmäßiger Dicke erreicht.

Title: New process for the synthesis of n alpha-fluorenylmethoxycarbonyl-ng-trityl-arginine
IPC: C07C279/14
Filed: 1989-12-18
Abstract: An improvement is described in the synthesis method for N α -trityl-­
N G -trityl-arginine within a process for preparing N α -fluorenyl­
methoxycarbonyl-N G -trityl-arginine from arginine, comprising: 
   a) forming N α -trityl-N G -trityl-arginine    b) selectively detaching the trityl group from the α-NH₂ and    c) introducing the fluorenylmethoxycarbonyl group in its place.     
     The improvement consists of preparing the N α -trityl-N G -trityl-­
arginine by solubilizing the arginine in an aprotic organic 
solvent by tri-alkylsilylation both of the amino nitrogen and of 
the carboxyl group, followed by tritylation, with trityl chloride, 
of the α-amino nitrogen, and of the guanidino group after 
deprotonating this latter with a bicyclic guanidine.  
     The new improved process can also lead to variable quantities of 
the arginine analogue di-tritylated at the guanidino group, namely 
N α -fluorenylmethoxycarbonyl-N G -di-trityl-arginine. This new 
compound, to which the present invention also relates, can also be 
used as such in peptide synthesis.
