Dark Stool: If your stool is black or bright red in color, it can mean that you are bleeding internally, as a possible result of an ulcer or cancer, and warrants a call to your doctor even if you think it could be hemorrhoids, or tiny tears in the anal tissue, due to constipation and straining.
The chemical reaction in which high molecular mass molecules are formed from monomers is known as polymerization. There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization.
Condensation polymers are any kind of polymers formed through a condensation reaction âwhere molecules join togetherâ losing small molecules as by-products such as water or methanol, as opposed to addition polymers which involve the reaction of unsaturated monomers.
