Condensation polymerizations are based on the releasing of water after the undergoing chemical reactions. In this manner, an illustrative example is shown below:
This is caused by high reactivity of the hydroxide ions when they are together allowing the polymerization to take place.
Scientists often communicate their research results in three general ways. but this only asks for 2 so I'm giving 2 haah anyway .One is to publish their results in peer reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to there presentations or presentations in general.
