He aha ka Cyclobutane-1,2,3,4-tetracarboxylic Dianhydride (CBDA) Me Cas 4415-87-6?

Hoʻohana ʻia ka Cyclobutane-1,2,3,4-tetracarboxylic dianhydride a me ka diamine monomer no ka hoʻomākaukau ʻana i kahi polyimide (PI), ʻo ke ʻano o ka polyimide he mau ʻano uila maikaʻi loa a me ke ʻano optical, me ka mea i hoʻomākaukau ʻia ai ka kiʻiʻoniʻoni PI, me ka loaʻa ʻana o kahi kiʻekiʻe kiʻekiʻe e ʻike ʻia ma waho, a hiki ke kū i nā mahana kiʻekiʻe kanakolukūmāhā Baidu. He maikaʻi loa kāna hana, ʻo ia ka hoʻomākaukau ʻana i kahi hōʻike kristal wai me kahi mea kūpono no ke kiʻiʻoniʻoni.
