Polymer Sci. 41 80 A decrease in polymerization temperature could result in increased regularity as a result of a simultaneous improvement in stereoregularity, linearity, and head-to-tail structure. 1964 Jrnl. Polymer Sci. 2 a. 4642 Stereoregularity was noticed in acetaldehyde polymerization only when solid borontrifluoride-etherate was used as the initiator. 1976 Makromol. Chemie CLXXVII. 1475 The four catalyst systems employed for the cis polymerization..give polymers with a different degree of stereoregularity. This could depend on a different stereoregulating power of the catalysts. 1979 Jrnl. Polymer Sci.: Polymer Chem. Ed. 17 2022 There was no significant difference between the stereoregularities of the polymers obtained with cesium naphthalene and fluorenylcesium as catalyst. This result indicates that the difference in initiator anions..did not affect stereoregulation. < as lemmas |
