WebPolymer Chain Lengths • Many polymer properties are affected by the length of the polymer chains. For example, the melting temperature increases with increasing molecular weight. • At room temp, polymers with very short chains (roughly 100 g/mol) will exist as liquids. • Those with weights of 1000 g/mol are typically waxy solids and soft ...
