The block copolymers of poly(butylene succinate) (PBS) and poly(butylene terephthalate) (PBT) were synthesized by melt processing for different times. The sequence distribution, thermal properties, and crystallization behavior were investigated over a wide range of compositions. For PBS/PBT block co

Experimentally synthesized poly(1,4-butylene terephthalate-co-tetramethylene oxalate) (PBT-PTMO) monofilaments were evaluated for hydrolytic stability in salt water (SW) and distilled water (DW) at temperature below and above glass transition temperature (T g ), along with commercially available pol
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 streng
