We know from the periodic table that a carbon atom has 4 valence electrons in the outermost shell.   In order for the atom to be more stable, the outermost shell must be filled up. Carbon follows the octet rule Read More …

Condensation polymers are any kind of polymers formed through a condensation reaction where molecules join together–losing small molecules as by-products such as water or methanol.

In addition polymerization, all the original atoms present in the monomers are retained in the polymer product.

Plastic classifications is a system established to allow consumers to properly recycle and dispose of different types of plastics. Manufactures follow a coding system and place an SPI code on each plastic product, and are usually printed or modeled into the bottom.

Polymerization is simply the process of putting together monomers (single molecules), to become a long chain of molecules (called polymers) with the use of a catalyst.
