The method allows for the production of polyolefins of low molecular weights and narrow molecular weight distributions.

Both the molecular weight distribution of the sample and the average molecular weights (Mn, Mw) can be determined using GPC.

Alternatively, the following molecular masses may be used

The polydispersities are dependent on the molecular weights of the standards.

Mixtures of molecular weights may also be used.

The molecular weights of the sample determined in this way are relative values and are described as polystyrene equivalent molecular weights.

The second reaction zone is operated to produce a copolymer having a second molecular weight distribution different from the first molecular weight distribution.

The molecular masses of molecules in the de novo sequence are compared to molecular masses of molecules in each sequence in the sequence database.

This method permits to determine the molecular weight distribution and the average molecular weights (Mn, Mw).

The polymer produced according to this invention has a broad molecular weight distribution.

The methods preferably compare the molecular masses of subsequences generated from the target sequence with predicted molecular masses by a database look-up step.

The system also receives an indication of the molecular weights detected when analyzing the biomolecules to which the molecular tags have been associated.

The acrylic adhesive layer has a molecular weight distribution of 2.4—4.4.

Narrowly distributed, linearly constructed polystyrene standards with known average molecular weights Mn and Mw and a known molecular weight distribution are normally used for this.

Both have molecular weights of 40 kDa and isoelectric points of 3.9.
