Linear Polymer

Polymers with one-dimensional linear chains are called linear polymers. Because the chains are well packed with high magnitude of intermolecular forces of attraction, therefore they have high densities, high melting points and high tensile strength. Linear polymers can be divided into two groups: homopolymer and copolymer. If a polymer consists only one kind of monomer unit, it is homopolymer, like polystyrene. A polymer consists more than one kind of monomer, it is copolymer, like polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA). Homopolymers possess a greater degree of regularity in their structure so they always have high crystallinity. Copolymers can provide improved characteristics than homopolymers because of advantages on both monomer units. For example, polypropylene is copolymerized by propene and ethylene, it offers better chemical resistance and impact resistance than the homopolymer polyethylene. At Matexcel, we can synthesize different linear polymers based on your research needs.
