To determine why poly(acrylic acid) has a higher T g than poly(vinyl chloride). Concept introduction: Polar molecules can participate in dipole–dipole interactions, so they generally have higher melting points than nonpolar molecules with similar molar masses. Similarly, poly(vinyl chloride), a polar polymer, has a significantly higher T g than polypropylene, a nonpolar polymer, even though both polymers have similar molar masses
