Abstract:
An aqueous adhesive composition and a process for preparing such compositions are disclosed. The composition comprises macromolecular complex comprising (A) a first component comprising (i) a framework element and (ii) a polyphenol, and (B) second component comprising a polypeptide, oligopeptide, amino acid, or polyamine. The 5 framework element comprises (a) a polypeptide, oligopeptide, amino acid, or polyamine, (b) a polysaccharide, oligosaccharide, or monosaccharide, or a saccharide conjugate, or (c) a lignin, a lignan or a lignin conjugate. The polyphenol comprises a tannin, a tannic acid, a flavonoid, or a poly-resorcinol. An adhesive precursor composition comprising the first component is also disclosed.
Abstract:
The invention relates to a copolyamide containing at least two patterns and of the general formula A/(Cz diamine). (Cw diacid), in which : z is the number of carbon atoms of the diamine and w is the number of carbon atoms of the diacid; and A is selected from a pattern obtained from an amino acid and a pattern of the general formula (Cx diamine). (Cy diacid), wherein x is the number of carbon atoms of the diamine and y is the number of carbon atoms of the diacid; the amino acid, each diamine and each diacid being obtained from a renewable raw material according to the ASTM D6866 standard. The invention also relates to a composition containing the copolyamide, and to the use of this copolyamide and of the composition, essentially for producing thermofusible glues, in any form thereof.

Abstract:
The invention provides, in a first embodiment, a blocking wax composition. The blocking wax comprises from about 50 to about 90 weight percent of a water-soluble continuous phase and from about 10 to about 50 weight percent of a discontinuous solid phase filler that is substantially inert to the continuous phase. The invention further provides a method for mounting a contact lens blank for machining.
Abstract:
The invention relates to a particle-shaped binding agent agglomerate, containing at least one natural or synthetic polysaccharide and one synthetic polymer, whereby a 5 wt. % aqueous solution or dispersion of particles with a particle diameter having an over average particle variable interval (Tm) and an aqueous dispersion of particles with a particle diameter having an under average particle variable interval (Tm) after a dissolution time of 1 hr or less, respectively exhibit a viscosity which deviates by less than 20 % from the other respective viscosity. The invention also relates to a method for producing said particle-shaped binding agent agglomerate, in addition to the use thereof.
