Antifog polyethylene (PE) films are widely used as covers for greenhouse structures because they can eliminate the multiple adverse effects of the fogging phenomenon. Herein, we propose a way to enhance the shelf life of antifog PE films by delaying the migration of antifogging agents using polymer microspheres. Crosslinked poly(maleic anhydride-styrene-divinylbenzene) microspheres (PMSD) were prepared by self-stabilized precipitation polymerization (2SP) and then converted into PMSD grafted with methoxy polyethylene glycol (mPEG) of different chain lengths (PMSD-g-mPEG). PMSD-g-mPEG microspheres were incorporated into PE films with an antifogging agent, and the properties of the prepared antifog PE films were investigated in detail. SEM displayed the good dispersion state of PMSD-g-mPEG at low loadings and its pos. correlation with mPEG chain length. Accelerated dripping experiments and contact angle tests showed that PMSD-g-mPEG2000 microspheres can exert the best effect in delaying the migration of antifogging agents, giving rise to a 36% improvement in dripping duration under optimized conditions. In addition, PMSD-g-mPEG2000 microspheres do not affect the optical, mech., and thermal properties of antifog PE films obviously. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Safety of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).
2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
