Molecular formula :
nature : also known as polymerization (reaction). Several saturation is not the ring or the participation of the monomer polymerization reaction. For example, butadiene and styrene copolymer derived by SBR (styrene-butadiene rubber). According to various monomer in the resulting copolymer with the chain can be divided into random copolymer, alternating copolymer, block copolymer (or mosaic copolymer) and the graft copolymer.
