Sentence examples for methyl side group from inspiring English sources
Indicative of a free volume increase, a molecular energetic mobility analysis (involving intrinsic friction analysis) revealed enhanced methyl side group mobility.
Adding methyl side group substituents to the ortho position of the biphenol group restricts the subglass γ process in a kinetic sense, shifting the process to higher temperatures.
At temperatures above the glass transition temperature (Tg) there are two major molecular motions in this copolymer: a backbone motion (the rotational motion about single bonds) and a methyl side group rotation.
This is based on the existence of perfect matching between the interchain distance of β-PBA along [100] direction and the distance of the out-sticking methyl side group arrays along the [101] direction of the (010) iPP plane.
As the temperature is further decreased to about −175°C, well below the β-transition observed in d.m.a., the methyl side group rotation slows down, suggesting that the methyl rotation may be associated with the observed β relaxation process.
