Process for producing block copolymer pigment dispersants

Номер: US20120041138A1
Автор: Sheau-Hwa Ma
Принадлежит: EI Du Pont de Nemours and Co

The present invention is a process for producing a linear block copolymer, useful as a dispersant for pigment, wherein the block copolymer comprises acetoacetyl amine functional groups which serve as pigment anchoring groups. The linear block copolymer can be an AB, ABC, or ABA block copolymer. The linear block copolymer produced by the present invention can be useful in dispersing and stabilizing a wide range of pigments in solvent based systems, and are particularly useful in providing pigment dispersions that are used in coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.

An extended film and a manufacturing method thereof are provided. The extended film includes a poly(lactic acid) and a block copolymer, wherein the block polymer includes a first block, a second block and a third block that connected with each other by chemical bonds. The extended film is formed by steps of mixing poly(lactic acid) and the block copolymer to form a mixture, compressing the mixture to form a board body and extending the board body to form an extended film, thereby forming an extended film having properties of high thermal-resistance and high transparency, the film thus obtained is applicable for packaging use. 1. An extended film , comprising:poly(lactic acid), anda block copolymer comprising:a first block having segments formed by a styrene repeating unit;a second block having segments formed by at least one repeating unit selected from the group consisting of acrylate repeating units and methacrylate repeating units; anda third block having segments formed by an ethylenical repeating unit having epoxy groups,wherein, the first block, the second block and the third block are connected by chemical bonds.4. The extended film of claim 1 , wherein the styrene repeating units are formed by at least one monomer selected from the group consisting of styrene claim 1 , α-methyl styrene claim 1 , m-methyl styrene claim 1 , o-methyl styrene claim 1 , p-methyl styrene claim 1 , o-ethyl styrene claim 1 , p-ethyl styrene and p-tert-butyl styrene;the acrylate repeating units are formed by at least one monomer selected from the group consisting of methyl acrylate, ethyl acrylate, n-propyl acrylate, n-butyl acrylate, tert-butyl acrylate, n-hexyl acrylate, cyclohexyl acrylate, 2-ethylhexyl acrylate, lauryl acrylate, isobornyl acrylate, cyclododecyl acrylate, chloromethyl acrylate, 2-chloroethyl acrylate, 2-hydroxyethyl acrylate, 3-hydroxypropyl acrylate, 2,3,4,5,6-pentahydroxyhexyl acrylate, and 2,3,4,5-tetrahydroxypentyl acrylate;the methacrylate repeating units are ...
