发明人：LAFERTE OLIVIER
权利人:BOSTIK SA
摘要:The present invention provides a process for the synthesis of silylated polyurethanes, comprising three sequential steps, a step (i) of preparing NCO-terminated polyurethane, a step (ii) of partial grafting of the NCO functions with silane functions and a step (iii) of total grafting of the residual NCO functions with functions that react with the NCO functions by means of polyfunctional compounds. The present invention also provides a silylated polyurethane composition that can be obtained by means of the process according to the invention, an adhesive composition comprising said silylated polyurethane composition and a self-adhesive item obtained from the adhesive composition according to the invention.

标题 :Process for the production of graft polymers
发明人：WENZ ECKHARD; BUCHHOLZ VERA; EICHENAUER HERBERT; WOLF UDO; BORN RALF-JURGEN; JANSEN ULRICH; DIETZ WOLFGANG
摘要:A process of preparing a graft polymer (e.g., an ABS graft copolymer), which involves determining the concentration of at least one reaction component during the course of the reaction by means of Raman spectroscopy, is disclosed. The process, more particularly, comprises: (a) synthesizing the graft polymer from a reaction mixture comprising reactive components (e.g., monomers such as styrene and acrylonitrile, and a graft base); (b) analyzing the reaction mixture, at intervals, during the synthesis of the graft polymer, by means of Raman spectra; (c) recording the results of the Raman spectra analysis; (d) determining the concentration of at least one of said reactive components (e.g., styrene) by means of spectral evaluation of the recorded Raman spectra; and (e) terminating the synthesis reaction of the graft polymer when the concentration of at least one of the reactive components has reached a predetermined concentration value.

摘要:There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less. The nano-elements of CSSC can be capable of stimulating the synthesis of skin proteins and/or enabling the delivery of active agents upon their application to a surface to be treated therewith. Methods for preparing the compositions and uses thereof are also provided.
