Title
(JA) ディップ成形品の製造に好適なポリマーラテックス
Abstract
(JA)

【解決手段】本発明は、ラジカル乳化重合によって作られたポリマーラテックスであって、少なくとも1つの共役ジエン成分に由来する構造単位を含有するポリマー粒子を含み、該ポリマー粒子は、最低でも50℃のガラス転移温度(Tg)を有する少なくとも1つの硬質相部分、および最高でも10℃のガラス転移温度(Tg)を有する少なくとも1つの軟質相部分を含み、ポリマー粒子の総重量に対して硬質相部分の総量が2〜40重量%であり、軟質相部分の総量が60〜98重量%であり、Tgは、ASTM D3418-03に従ってDSCで測定し、該ポリマーラテックスは、臨界凝集濃度として測定した電解質安定性(pH10で0.1%のラテックスの総固体含量を測定)が30mmol/l CaCl2未満であり、ディップ成型品の製造に特に好適なポリマーラテックスに関する。さらに、本発明は、このようなポリマーラテックスの製造方法、ディップ成型品の製造のための該ポリマーラテックスの使用、ディップ成型品の製造に好適な複合ポリマーラテックス組成物、ディップ成型ラテックス品の製造方法、およびそれによって得られるラテックス品に関する。
