2.Phenolic resin was modified respectively using four latexes of butyronitrile-butadiene,carboxylic butyronitrile-butadiene,styrene-butadiene and pyridine-butadiene.
7.Using the method of latex polymerization,poly vinyl acetate was synhesized with PVA as protective colloid,which was crosslinked with formylamine-group containing component.
8.The process of change for thermo-oxidative degradation of latex film at different vulcanization time during the prevulcanization of latex by peroxide was studied by using of TG-DTG and DTA.
9.Unlike traditional latex or acrylic coatings, polyurea, as a suitable waterproofer even under seawater immersion, is in no way influenced by ponding water, which is very often on existing roofs.
