mass polymer造句

• The term " oxide " or other terms are used for high molar mass polymer when end-groups no longer affect polymer properties.
• High-pressure aeroponics systems include technologies for air and water purification, nutrient sterilization, low-mass polymers and pressurized nutrient delivery systems.
• The term glycol is reserved for low to medium range molar mass polymer when the nature of the end-group, which is usually a hydroxyl group, still matters.
• "High Number-Average Molecular Mass Polymers " may be obtained only with a high "'fractional monomer conversion "'in the case of step-growth polymerization, as per the Carothers'equation.
• Such a device composed for example of arranged ultra-high molecular mass polymer fibres ( Helicene, Polyacetylene ) could store extraordinary ( 0.1-10MJ / kg in comparison to 0.0003MJ / kg of clockwork spring ) amount of energy which can be stored and released almost instantly, with high energy conversion efficiency.
• As an example of copolymerization of non-homopolymerizable monomers, ?-butyrolactone ( BL ) and ?-caprolactone ( CL ) show that the copolymerization provides high molar mass polymers : The BL / CL copolymer synthesis is viable despite the fact that BL monomer addition to its own  bl * active chain ends was highly reversible, as the  bl * unit could be blocked via a practically irreversible CL addition.
