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.

## Abstract Crystal growth of the trigonal form of isotactic poly(buteneβ1) (__it__βPB1) was successfully observed in the melt at atmospheric pressure. The growth rate of trigonal crystals was obtained by __in situ__ optical microscopy. It is one hundredth that of __it__βPB1 tetragonal crystals. Th
A study has been carried out of the physical and mechanical properties and crystallization behavior of poly-&methyl-1-butene (poly-3-MB). The melt behavior of poly-3-MB waa examined by means of the depolarised light intensity (DLI) technique. These birefringence studies indicated the onset of motion
