Chlorine-induced cracking of acetal resin plumbing joints and polybutylene pipes has caused many serious floods in domestic properties, especially in the US in the 1990s. Like tensile strength, this is highly relevant in polymer applications involving the physical properties of polymers, such as rubber bands.

You are … [35] One important example of the physical consequences of the molecular weight is the scaling of the viscosity (resistance to flow) in the melt. These are the properties that dictate how the polymer actually behaves on a macroscopic scale. In other words, miscible materials usually form a solution not because their interaction with each other is more favorable than their self-interaction, but because of an increase in entropy and hence free energy associated with increasing the amount of volume available to each component. googletag.pubads().set("page_url", "https://dictionary.cambridge.org/dictionary/english/polymer"); Many commonly used polymers, such as those found in consumer products, are referred to by a common or trivial name. { bidder: 'appnexus', params: { placementId: '11654149' }}, Coatings Cathodic Protection Surface Preparation CUI Inspection / Monitoring Asset Management Materials Selection Soluble Salts. { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_Billboard' }}, Dipole bonding is not as strong as hydrogen bonding, so a polyester's melting point and strength are lower than Kevlar's (Twaron), but polyesters have greater flexibility.

The number-average molecular weight (Mn) and weight-average molecular weight (Mw) are most commonly reported. When heated above 450 °C, polyethylene degrades to form a mixture of hydrocarbons. Polymer definition, a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper.
