โฆ Synopsis
A few percent of poly(butylene)-b-poly(tetramethylene glycol) was able to turn a liquid plasticizer into a gel, and thus imparted yield stresses to the fluid. When the plasticizer contained as little as 2.5 wt % of the block copolymer, sag free plastisols were obtained. A reduction in tensile strength was found for the modified plastisols, while the elongation was not affected.

Poly(ethy1ene terephthalate) copolymers were prepared by melt polycondensation of dimethyl terephthalate and excess ethylene glycol with 10- 40 mol% (in feed) of poly(ethy1ene glycol) (E) and poly(tetramethy1ene glycol) (B), with molecular weight (MW) of E and B 200-7500 and 1000, respectively. The
The poly(ethylene glycol) (PEG)-grafted styrene (St) copolymer, which was formed as a nanosphere, was used as an agent to modify the surface of poly(ethylene terephthalate) (PET) film. The graft copolymer was dissolved into chloroform and coated onto the PET film by dip-coating method. The coated am
Thermoplastic elastomers based on poly (butylene terephthalate) (PBT) and poly (ethylene glycol) (PEG) were studied by bending-creep measurements. The dependence of the creep compliance on the composition of the block copolymer was determined, and the experimental results were compared with calculat
