Abstract: A (co)polymer structure comprising at least one portion of an acrylic, silicone, polyglycolic, polysaccharide or natural polymeric chain, comprising a plurality of functionalized units of general formula (I): wherein [C-A] is a portion of a polymeric or copolymeric chain selected from an acrylic silicone, polyglycolic, polysaccharide polymeric structure or from a natural polymer, and X is a functional group selected from one or more solfonic, carbossilic, amino acidic or epoxide groups to react at room temperature and in reaction conditions suitable for use on living beings and to form ionic or covalent bonds with keratin in absence of preemptive modifications of the polymer chain itself.

Abstract: Novel (co)polymeric structures having functional groups making possible, under conditions that are safe for human use, the formation of chemical bonds with human keratin, and in particular with the keratin present in hair, eyelashes and eyebrows, skin, nails, lips, the oral mucosa and tissues of the external genital organs are disclosed; the invention also relates to the synthesis of such (co)polymeric structures and the use thereof in the fields of cosmetics and medicine.

Abstract: A decorative glass for lamps comprises a fastening device formed as a single body and able to allow direct association with a lamp holder. The fastening device preferably comprises a thread formed on the inner side of a surface portion of the glass.

Abstract: The invention relates to build-up agents which comprise a condensation product among an aldehyde, a phenol compound and an aromatic carboxylic acid, hydroxy-substituted on the aromatic nucleus. The products are particularly effective in reducing or suppressing the build-up formation in the polymerization of vinyl chloride or vinyl acetate, other copolymerizable substances being optionally present. Further objects of the invention are compositions containing the above agents, their use as build-up agents, methods for their preparation and the products obtained therefrom, the polymerization processes carried out in reactors whose inner walls are coated with these agents and polymers obtained from these process.

Abstract: Cross-linked copolymers possessing high thickening and suspending properties obtainable by polymerization of monomeric systems comprising a) 10-97% of at least one unsaturated carboxylic acid, b) 0-80% of at least one alkyl ester of an unsaturated acid, c) 0.5-80% of an associative monomer, d) 0-20% of an unsaturated amide, e) 0.2-20% of a suitable cross-linking agent and f) 0-20% of an unsaturated sulfonic acid; processes for their preparation, which comprise polymerization by precipitation, suspension and solution polymerizations or emulsion polymerization; latexes comprising up to 50% or more of said copolymers; said cross-linked copolymers and said latexes whenever prepared by the above polymerization processes; their use as thickening agents of aqueous, or substantially aqueous systems; and the new cross-linking agents.

Abstract: The present invention relates to a process for the preparation of crosslinked polymers and copolymers of acrylic acid and methacrylic acid of formula ##STR1## wherein R.sub.1 is hydrogen or methyl. Said process, using ethyl formate as solvent, allows to obtain polymers having low residue of monomer and of solvent and with higher thickening capacity.
