TL;DR: The Tg-composition curves of the five miscible blend systems can be described by the Gordon-Taylor and the Kwei equations as mentioned in this paper, and they show a positive deviation in their glass transition temperatures.
Abstract: Poly(p-vinyl phenol) is miscible with poly(methyl methacrylate), poly(ethyl methacrylate), poly(n-propyl methacrylate), poly(isopropyl methacrylate), and poly(tetrahydrofurfuryl methacrylate), but is immiscible with poly(n-butyl methacrylate). Except for poly(p-vinyl phenol)/ poly(methyl methacrylate) blends, the other miscible blends show pronounced positive deviations in their glass transition temperatures. The Tg-composition curves of the five miscible blend systems can be described by the Gordon-Taylor and the Kwei equations.

TL;DR: In this article, it was shown that poly(tetrahydrofurfuryl methacrylate) (PTHFMA) is miscible with poly(hydroxy ether of bisphenol A) (phenoxy) as shown by the existence of a single glass transition temperature in each blend.
Abstract: Poly(tetrahydrofurfuryl methacrylate) (PTHFMA) was found to be miscible with poly(hydroxy ether of bisphenol A) (phenoxy) as shown by the existence of a single glass transition temperature in each blend. PTHFMA/phenoxy blends containing 50% or less of PTHFMA showed reversible lower critical solution temperatures. PTHFMA was judged to be miscible with poly(styrene-co-allyl alcohol) based on the optical clarity of the blends.

TL;DR: The Brillouin spectrum of polyethylene has been measured as a function of temperature and slope discontinuities of opposite directions have been observed in the shift and width near the glass transition temperature, attributed to a corresponding discontinuity in the temperature coefficient of specific volume, while the onset of long-range coordinated molecular motion near the transition region.
Abstract: The Brillouin spectrum of polyethylene has been measured as a function of temperature. Slope discontinuities of opposite directions have been observed in the Brillouin shift and width near the glass transition temperature. The former is attributed to a corresponding discontinuity in the temperature coefficient of specific volume, while the latter to the onset of long-range coordinated molecular motion near the transition region.

TL;DR: Sterically hindered amine groups were incorporated into poly(methy1 methacrylate) and poly(ethy 1 methacylate) by copolymerizing 2,2,6,6 tetramethylpiperidinyl methACrylate (TPMA) with MMA and EMA as mentioned in this paper.
Abstract: Sterically hindered amine groups were incorporated into poly(methy1 methacrylate) and poly(ethy1 methacrylate) by copolymerizing 2,2,6,6 tetramethylpiperidinyl methacrylate (TPMA) with MMA and EMA. The replacement of the pendant alkyl groups of the polymethacrylates by SHA groups reduced their miscibility with poly(styrene-co-acrylonitrile) (SAN) and with poly(α-methyl styrene-co-acrylonitrile) (MSAN). The cloud points of the miscible blends indicated that the effective interaction parameter B of a blend became less negative with increasing TPMA content in the copolymer, and B was more negative for SAN blend than for a corresponding MSAN blend.
