LDPE (Low Density Polyethylene) is defined by a density range of 0.910 - 0.940 gcm3. It has a high degree of short and long chain branching, which means that the chains do not pack into the crystal structure as well. It has therefore less strong intermolecular forces as the instamore...
Polymers are substances containing a large number of smaller, identical molecules (called monomers) linked together. These substances often form into a chain-like structure. Polymers have extremely high molecular weights and the chains may differ from one another in their moleculmore...
