  • ADHESIVE COMPOSITION FOR A HUMID MEDIUM, BASED ON BLOCK COPOLYMERS COMPRISING AT LEAST ONE HYDROPHILIC BLOCK
    Publication number: 20080275375
    Abstract: The invention relates to a block copolymer which is produced by a controlled radical polymerization, has an individual composition and structure and is used for adhesion in a humid medium The inventive copolymer comprises a continuous flexible and water repellent matrix (of elastomer nature) and a dispersed phase in the form of hydrophilic nanodomains. Said copolymer exhibits an excellent adhesion as a result of the structure thereof also in a very humid medium.
    Type: Application

  • Adhesive composition for a humid medium, based on block compolymers comprising at least one hydrophilic block
    Publication number: 20060052545
    Abstract: The invention relates to a block copolymer which is produced by a controlled radical polymerisation, has an individual composition and structure and is used for adhesion in a humid medium. The inventive copolymer comprises a continuous flexible and water repellent matrix (of elastomer nature) and a dispersed phase in the form of hydrophilic mechanisms. Said copolymer exhibits and excellent adhesion as a result of the structure thereof also is a very humid medium.

  • Low-temperature film-forming latex based on hydrophobic polymers having a core/shell structure without coalescents
    Patent number: 6723779
    Abstract: A latex which forms a film by evaporation at a temperature of less than 40° C. is based on hydrophobic polymer particles having a core/shell structure. The particles consist of 70 to 90% by weight of at least one polymer with a soft character having a glass transition temperature of less than 20° C. forming the core, and 10 to 30% by weight of at least one polymer with a hard character having a glass transition temperature of greater than 50° C. forming the shell. When applied to any surface and after drying at low temperature, the latex, without the use of any coalescents or volatile organic compounds, provides a continuous film which is homogeneous, has no surface tack and has good mechanical integrity.
