Disclosed is a fastening structure for a seating foam, comprising a foam and a reinforcement fabric, and characterized in that the fastening structure is directly provided at a reinforcement fabric at a location corresponding to a fastening position, and is connected to the reinforcement fabric. The fastening structure of the present invention simultaneously meets two functional requirements of a foam, namely reinforcement of a side B of the foam and fastening of an exterior side A of the foam. The novel fastening structure of the present invention saves space, is thin and light, enhances the strength of the foam against a pull-out force, and optimizes a foam production process.

The present disclosure relates to a liquid dispersant of the formula I 

Polyethylene imine based dendritic dispersant

A method for producing an AB block copolymer with PDI is provided. The method comprises steps of:

Method for producing block copolymers

The invention relates to a liquid dispersant based on polyamine-graft-polyacrylate blend, its preparation and its use in solvent borne systems, especially to a polyamine-g-polyacrylate grafted copolymer blend of the general formula (1) or a mixture of formula (1) and YT-(A1,A2)-Y1 wherein T is a polyamine or polyimine, A1 is a bridging bond which is selected from amide or amide, A2 is a &#x2014;N&#x2014;C&#x2014; bridging bond, Y is an acrylate residue of the general formula (2), wherein, Rand Rare, independently, hydrogen or Calkyl, aryl, heteroaryl, substituted aryl. n is a number of 1-1000, wherein the polyamine-g-polyacrylate grafted copolymer blend has an average molecular weight of 50 000 g/mol to 150 000 g/mol and a polydispersity M/Mis greater than 3. 

Polyamine-polyacrylate dispersant

This invention refers to a novel process for the synthesis of polyethylene imine (PEI)-based pigment dispersants characterized by a 'grafting from' approach, allowing the manufacture of solvent based dispersant systems. The polyethylene imine (PEI)-based pigment dispersant can be presented by the formula (I) X-(T)-P-(T)-H wherein P is a polyethyleneimine (PEI) back-bone; T is a residue &#x2014;CO-A-O&#x2014; wherein A is C-Calkylene optionally substituted with C-Calkyl with the proviso that each linkage between P and T is an amide bond and each linkage between X and T is an ester bond, X is a modifier or terminator residue R&#x2014;CO&#x2014; wherein R is a linear or branched, saturated or unsaturated alkanecarboxylic acids having from 1 to 22 carbon atoms or an unsaturated fatty acid residue or a hydroxycarboxylic residue or a polyester residue obtained from polycondensation of hydroxycarboxylic acids, or an acid terminated polyether; n, m independently are a number from 1 to 100.
