## Abstract To enhance durability of poly(vinyl alcohol) (PVA)/iodine polarizing film under humid and warm atmospheres and to identify the effects of syndiotacticity on the polarizing efficiency (PE) and durability of PVA/iodine complex film, we prepared three high molecular weight (PVA)s with simi
To enhance the physical properties of syndiotacticity-rich (syndiotactic diad content 63ร4%) ultra-high molecular weight (UHMW) (number-average degree of polymerization 12 300) poly(vinyl alcohol) (PVA) รlm, it was solution blended with rigid-rod imogolite in dimethyl sulphoxide. In addition, the bl
Vinyl pivalate (VPi) was polymerized in bulk by ultraviolet-ray initiation at low temperatures using 2,2-azobis(2,4-dimethylvaleronitrile) (ADMVN) and 2,2'-azobis(isobutyronitrile) (AIBN) as photoinitiators. High molecular weight (HMW) poly(vinyl pivalate) (PVPi), having a number-average degree of p
