  Provided are a thermal stabilizer for polyvinyl chloride, comprising a mixed powder (P) containing a vinyl alcohol-based polymer (A) having an average degree of saponification from 30 to 99.9 mol% and having a viscosity average degree of polymerization of 1000 or less, and a zinc compound (B), wherein a weight ratio A/B of (A) and (B) falls within a range from 1/10 to 10/1, and the mixed powder (P) has 80 weight% or more of particles passing through a screen with 75 µm openings, and a polyvinyl chloride resin composition, comprising: from 0.1 to 10 parts by weight of the thermal stabilizer for polyvinyl chloride based on 100 parts by weight of a polyvinyl chloride resin. Such polyvinyl chloride resin composition is excellent in the thermal stability while being molded and allows obtaining a less colored molded article.

  本发明提供了一种聚氯乙烯热稳定剂，包括一种混合粉末（P），其中含有一种乙烯醇基聚合物（A），其平均皂化度为 30 至 99.9摩尔％、粘度平均聚合度为1000或更低的乙烯醇基聚合物(A)和锌化合物(B)，其中(A)和(B)的重量比A/B在1/10至10/1的范围内，混合粉(P)中有80重量％或更多的颗粒通过开口为75微米的筛网，以及一种聚氯乙烯树脂组合物，其中包括：以100重量份的聚氯乙烯树脂为基准，0.1至10重量份的聚氯乙烯热稳定剂。这种聚氯乙烯树脂组合物在模塑过程中具有优异的热稳定性，可获得着色较少的模塑制品。

  Compositions and methods for alleviating or preventing discoloration in flame-retarded flexible polyurethane foams, known as “scorching”, are provided. The anti-scorch compositions contain antioxidant agents combined with at least one, and preferably with two, additional compounds selected from β-diketone compounds, epoxy compounds, organic phosphites or phosphonites, and metal salts of carboxylic acids.
