Uses
Used in the Polymer Industry:
(Tetramethylcyclopentadienyl)zirconium trichloride is used as a catalyst for the production of polyethylene products with improved stiffness, toughness, and processability. Its high catalytic activity and selectivity enable the synthesis of polymers with tailored properties, such as increased molecular weight, narrow molecular weight distribution, and controlled branching. This results in polyethylene products with enhanced mechanical and thermal properties, making them suitable for a wide range of applications, including packaging materials, films, and pipes.
Check Digit Verification of cas no
The CAS Registry Mumber 304016-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,0,1 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 304016-43:
(8*3)+(7*0)+(6*4)+(5*0)+(4*1)+(3*6)+(2*4)+(1*3)=81
81 % 10 = 1
So 304016-43-1 is a valid CAS Registry Number.

Catalyst systems and methods for making and using the same. A method of methylating a catalyst composition while substantially normalizing the entiomeric distribution is provided. The method includes slurrying the organometallic compound in dimethoxyethane (DME), and adding a solution of RMgBr in DME, wherein R is a methyl group or a benzyl group, and wherein the RMgBr is greater than about 2.3 equivalents relative to the organometallic compound. After the addition of the RMgBr, the slurry is mixed for at least about four hours. An alkylated organometallic is isolated, wherein the methylated species has a meso/rac ratio that is between about 0.9 and about 1.2.
