Blends containing polyacetal and a random styrene-vinyl phenol copolymer consisting of 35 mol% vinyl phenol segments were prepared by melt mixing and found to exhibit miscibility within the amorphous phase. The blends exhibited a single, composition-dependent glass transition temperature as determined by dynamic mechanical measurements. Thermal analysis revealed a significant depression of the melting point and, in certain cases, a lowering of the degree of crystallinity of the polyacetal phase upon blending with the styrene vinyl phenol copolymer.
