摘要： The present invention relates to a method for reversibly bonding a first and a second substrate, wherein at least the first substrate is an electrically non-conductive substrate, the method comprising: coating the surface of the electrically non-conductive substrate(s) with a conductive ink; applying an electrically debondable hot melt adhesive composition to the conductive ink-coated surface of the first substrate and/or the second substrate; contacting the first and the second substrates such that the electrically debondable hot melt adhesive composition is interposed between the two substrates; allowing formation of an adhesive bond between the two substrates to provide bonded substrates; and optionally applying a voltage to the bonded substrates whereby adhesion at least one interface between the electrically debondable hot melt adhesive composition and a substrate surface is substantially weakened. Furthermore, the present invention relates to the bonded substrates thus obtained.

摘要： This invention discloses a process for preparing a branched polymer via emulsion polymerization at room temperature and is related to the field of polymer synthesis and preparation of functional polymers. A mixture of water as medium, anionic surfactant as emulsifier, sodium bicarbonate as pH regulator, the reductant monomer containing both polymerizable double bond and the reducing group combined with the persulfate as the oxidant to be useful as initiator, styrene, (meth) acrylate or vinyl acetate as monomer, is reacted to synthesize the branched polymers via a free radical in-situ emulsion polymerization at room temperature and ambient pressure. The monomer conversion can be above 85% in a range of about 10 mins to 10 hours of the reaction time. The process for preparing a branched polymer is carried out under the conditions of emulsion polymerization at room temperature and normal pressure without the addition or assistance of the branched monomer and other initiators. The advantages of this process are: it is a simple, feasible and stable polymerization process; no need to control temperature and pressure of the reaction; leads to low energy consumption, less impact on the environment, short reaction time and high monomer conversion; achieves high molecular weight and narrow molecular weight distribution of the branched polymers synthesized; results in low cost of the production owing to the direct use of commercial polymerizable reductant monomer in the reaction. The polymerization process of this invention also has many other advantages such as ease of operation, use of mild conditions, an environmentally friendly and low-cost process with a controllable degree of branching for the polymer, and highly suitable for synthesizing branched polymers from various monomers. The above advantages of this process are of great significance for the research and development and application of the branched polymers.

摘要： The invention relates to a copolymer obtained by polymerisation reaction of at least three comonomers: a first anionic monomer, a second monomer comprising an olefin unsaturation, and a third monomer comprising a hydrophobic group. The invention likewise relates to the use of said copolymer as a thickening agent, in particular in aqueous suspensions of mineral particles with high solids content. The copolymer according to the invention makes it possible to improve the compromise between viscosity with high shear gradient and viscosity with low shear gradient, while also improving water retention inside the suspension.
