6.Using the method of latex polymerization,poly vinyl acetate was synhesized with PVA as protective colloid,which was crosslinked with formylamine-group containing component.
采用乳液聚合的方法,以乙酰化聚乙烯醇为保护胶合成聚醋酸乙烯乳液,并用含甲酰胺基的乙组分与其交联。
7.Based on the laboratory experiments, MMH polymer MMH polysulfonate drilling fluids system is developed through analyzing the properties of positive colloid, polymers and polysulfonate muds.
8.Note the clear vacuoles in the colloid next to the epithelium where the increased activity of the epithelium to produce increased thyroid hormone has led to scalloping out of the colloid.
