Copolymer emulsion lattices based on styrene (St) with methacrylate monomers, were synthesized with composition ratio (5/5) in the presence of a co-surfactants that consists of dodecyl benzene sodium sulfonate with polyvinyl alcohol (DBSS/PVA) and DBBS with polyoxyethylene glycol monomethyl ether (DBBS/POE). The obtained latices were characterized by 1H NMR, rheological and morphological techniques. The effect of latices on the physicomechanical properties of ordinary Portland cement (OPC) pastes was investigated. The results showed that the addition of water mixed to the cement with copolymer improves most of the specific characteristics of OPC. 相似文献

The research we conducted shows the possibility of the directed adjustment of epoxy composite performance characteristics through the application of small additives of potassium polytitanate whiskers, the introduction of polyfunctional plasticizers with chemical and mechanical methods of activation of the whole composition and its components; this ensured the creation of a new generation of epoxy composites with high‐performance properties (breaking tension = 116 MPa and modulus of elasticity at bending = 3150 MPa, destructive tension under compression = 95 MPa, impact strength = 18 kJ/m2 that meets the requirements of most industries. © 2018 Wiley Periodicals, Inc.
