摘要:
The present invention relates to dispersions in an aqueous phase of forming coatings after curing. The composition which can be used for paint and varnish, made up of a dispersion comprising at least one aqueous phase and a population A of particles of (co)polymer(s) whose size is between 10 and 1000 nanometres, in which the particles have an accessible acidic (advantageously carboxylic) functional group content of between 0.2 and 1.2 milliequivalents/gram of solid matter and have an accessible alcoholic functional group content of between 0.3 and 1.5 milliequivalents/gram. Application to paint.
摘要:
Polymeric compositions well suited for conversion into electroconductive shaped articles, e.g., films, comprise at least one convertible polymer (Pm) and at least one amphiphilic organic compound (B) which comprises a charge transfer complex or a radical ion salt having the formula (I): D.sub.d A.sub.a Z.sub.z, in which D is an electron donor; A is an electron acceptor; Z is a doping agent which itself can be a non-amphiphilic electron donor or electron acceptor, with the proviso that at least one of D and A is amphiphilic and contains at least one saturated or unsaturated hydrocarbon substituent having at least 10 carbon atoms; d is a number equal to or greater than 0; a is a number equal to or greater than 0; and z is a number equal to or greater than 0, with the further proviso that at least one of the symbols d and a is a number greater than 0.
摘要:
The present invention relates to the use, as antiadhesive agents and/or water repellents, of grafted functionalized polyorganosiloxanes consisting of grafted copolymer moieties, derived from at least one ethylenically unsaturated monomer which may be polymerized via a radical route and from a functionalized polyorganosiloxane (I) containing similar or different moieties (I) of formula (I) R.sub.a Y.sub.b X.sub.c Si O.sub.(4-a-b-c)/2 (I) in which formula: R=C.sub.1 -C.sub.18 alkyl, X=C.sub.1 -C.sub.20 alkylated epoxyfunctional residue, Y=acrylate, and a, b, c=0, 1, 2 or 3 with a +b+c=0, 1, 2 or 3. These grafted functionalized POSs are used in the form of an aqueous dispersion for the production of an antiadhesive coating on a solid support, preferably chosen from sheets of polymer material or of paper, cardboard or the like, from tapes which are adhesive on their non-adhesive side, from intercalating films of double-sided adhesive tapes or from woven or nonwoven fibrous supports and/or composites or non-composites.

摘要:
The invention concerns nanocapsules, in particular with an average size less than 50 nm, consisting of an essentially lipid core liquid or semiliquid at room temperature, coated with an essentially lipid film solid at room temperature having a thickness of 2-10 nm. The invention also concerns a method for preparing same which consists in producing a reverse phase of an aqueous emulsion brought about by several temperature raising and lowering cycles. Said lipid nanocapsules are particularly designed for producing a medicine.
