High-density polyethylene, molecular weight averages with

High molecular weight HOPE is a special class of linear resins with molecular weights in the 200,000 to 500,000 range. Ultra high density polyethylene has an average molecular weight of over 3 million. 

Polymer molecular weight and molecule size. You are asked to compute the maximum possible separation between the ends of a high density polyethylene molecule with an average molecular weight of 100,000. 

For high density polyethylene the MWD represents one of the basic parameters which, together with average molecular weight, density, short and long chain branching content, determines the physical, mechanical and rheological properties of the polymer and therefore its end uses (Table 1). 

High density polyethylene (HDPE) is a linear polymer with a molecular weight of up to 200,000 g/mol. UHMWPE, in comparison, has a viscosity average molecular weight of 6 million g/mol. In fact, the molecular weight is so ultra-high that it cannot be measured directly by conventional means and must instead be inferred by its intrinsic viscosity (IV).
