摘要:
Environmentally friendly, high performance coating formulations and methods for their preparation are described. The coating formulations can be prepared as aqueous dispersions. The aqueous dispersions include a plurality of multiphase polymer particles and a C8-C18 alkyl alcohol alkoxylated phosphate ester surfactant. The multiphase particles include an acrylic-based copolymer derived from one or more (meth)acrylate monomers and at least one copolymerizable surfactant. Optionally, the acrylic-based copolymer is further derived from one or more acid monomers, one or more amide monomers, and/or one or more molecular weight regulators. Further described herein are products prepared from the aqueous dispersions, such as for high gloss and satin paint compositions, that can have a low VOC content.

摘要:
A reaction vessel for carrying out a chemical or biochemical reaction, such as a polymerase chain reaction, said vessel having a coating of parylene or a derivative thereof, on at least the surface which contacts reactants.
摘要:
A method for carrying out an isothermal nucleic acid amplification reaction at a predetermined temperature, said method comprising changing the temperature of the reaction mixture away from the said predetermined temperature and allowing it to return to the predetermined temperature at least once during the amplification reaction so as to cause a temperature oscillation in particular of up to 15° C., for example of from 2-10° C. Apparatus adapted to carry out the method forms a further aspect of the invention.
