Several works have appeared in recent years on the structure of (poly)3MB1 but showing remarkable divergence concerning the crystal lattice of this polymer. Particularly, in a paper by Huguet the structure is interpreted on the basis of a tetragonal lattice, which is here shown to be unacceptable.
Solution properties of a propylene-tetrafluoroethylene 0aTFE) copolymer were studied in a thermodynamically good solvent (tetrahydrofuran, THF) and in poor solvents (n-butyl acetate, methyl isobutyl ketone). Mark-Houwink relations were determined for the copolymer in particular solvents and unpertur
## Abstract A series of novel hexeneโ1โpropylene random copolymers with isotactic sequence of propylene was synthesized with a MgCl~2~โsupported Cr(acac)~3~ catalyst. The molecular weight distribution of copolymers and homopolymers was considerably narrower than that of typical polyolefins produced
