Vi. Tsvetkova et al., SYNTHESIS OF ELASTOMERIC POLYPROPYLENE IN BULK USING THE (2-PHIND)(2)ZRCL2 HOMOGENEOUS CATALYST, Vysokomolekularnye soedinenia. Seria A, 39(3), 1997, pp. 389-395
The effect of the conditions of propylene polymerization in a liquid m
onomer using a new homogeneous metallocene catalyst (2-PhInd)(2)ZrCl2
on the rate of polymerization, molecular mass, stereoisomer compositio
n, and elastic properties of PP was studied. It was found that the pre
pared polymer shows a stereoblock structure, has high molecular mass,
and exhibits rubber-like properties. After an elongation of 300%, the
residual strain is 31-68%.
