Homopolymer definition

Homopolymer means polypropylene polymers that have been polymerized into isotactic sequences of repeating propylene monomer units with essentially no repeating units of a monomer other than propylene;
Homopolymer means a high molecular weight compound comprised of repeating molecular units of a single compound;
Homopolymer means product resulting from the bonding or polymerization of several molecules of a single type, or monomer, which may have different properties according to their chemical nature. In the case of PVC resins, the monomer used for polymerization is vinyl chloride monomer (VCM), whose molecules, when linked together, generate what is called a homopolymer (many molecules of a monomer of the same nature chemically bonded).
