The hindered phenols with a tert-butyl (X = tert-butyl) and a methyl (R = methyl CH3) at the o-position of the hindered phenolic hydroxyl group can weaken the steric hindrance of the hindered phenolic hydroxyl group to some degree, and accelerate the rate of antioxidant reaction, thus making the new structure of antioxidant play an unexpected effect. Hoc novum structuram impediebat Phenols Antioxidant dicitur asymmetric impediebat phenols Antioxidant.
An asymmetricus impediebat phenolic structuram cum Tert-BUTYL Group et METHYL Group ad Hydroxyl Ortho-Position sat praesidio se. Et asymmetric impedimento phenolic antioxidant, cum II - Methyl - VI - Tertiariis Butyl phenol sicut ossa, non solum habet generalem proprietatibus impediebat phenolic stabilitatem et resistentia adumbrandum effectus. Ita quod est magis evident perficientur quam commensus ratio impediebat phenol, et idoneam ad scelerisque oxidatio applications.
An245, An1790 (tum an2777) et AO80 sunt tres commune asymmetric prohibet Phenols Antioxidants, inter quae est maxime late late usus est in humili.
An CCXLV est maxime idoneam ad stereobstructu phenolic antioxidants organicum polymers. Sicut antioxidant, quod est in processus et longa-term scelerisque stabilitatem emendationem styrene polymers ut coxis, MBs et Abs, Engineering plastics ut pom et Pom et polyurethane. Est etiam quod efficax torquem Termino PVC polymerization processus. Hoc productum habet non effectus in Polymer reactionem, propter altum impulsum polystyrene, polyvinyl chloride, potest addidit ad monomer ante polymerization.
Insuper ad copia situ Ordinarius pulveris, possumus providere XXXV% contentus de dispersionem, an245dw. Post multos annos productio experientia, in dispersionem liquidum produci et suppleverunt a nostris societas non facile ad stratify, quod est facilius dispergere quam pulveris, quod est pelagus antioxidant in PVC polymerization processus.
