Photo acid generator 원리
Webacid, formed by the initiator, continues the polymerization also in the absence of light. As disadvantages one must mention the inhibition by bases, and chain transfer resulting from impurities of water. Still the cationic photo-polymerization is a niche technique compared to the omni-present free radical photopolymerization moreover due to the Web光致酸产生剂是一种光敏感的化合物，在光照下分解产生酸(H+)。 在曝光后烘烤(PEB)过程中，这些酸会作为催化剂使得聚合物上悬挂的酸不稳定基团脱落，并产生新的酸。 悬挂基 …
