Block copolymers composed of poly(dimethylsi1oxane) segments linked to polypeptide have been synthesized by reacting primary mine-terminated silicone with N-carboxy anhydrides of amino acids. The mine-terminated silicone was prepared by reacting "living" polysilanolate with y-aminopropyltriethoxysil
## Abstract This paper describes an unusual contrast inversion phenomenon in TEM imaging of PFSβ__b__βPDMS block copolymer bulk samples. It is clearly observed especially in samples that show a lamellar morphology that the contrast inversion is accompanied by a contraction of the PDMS domains and a
## Abstract **Summary:** Analysis was made of the crystallization of the PET blocks in PET/PC copolymers as a function of the block length, varying from $\overline M \_{\rm n}$β=β5300 to 17100 gβΒ·βmol^β1^ (__X__~n PET~β=β28β89, PET monomeric sequences). Analysis was also made of a series of PET hom
