In the paper apply difunctional group titanate TPC-T to the interface of GFRP. 将双官能团的钛酸酯TPC-T应用于GFRP界面。
By definition an exclusively difunctional monomer can only give rise to a linear polymer. 按照定义，一个特定的双官能单体，仅仅能得到线型聚合物。
Clearly the principle requirement for a substance to be capable of forming a structural unit of a polymer chain is that it must be difunctional. 显然，对于能成为聚合物链结构单元的物质的基本要求是：它必须是双官能的。
The principle, process, various difunctional catalysts ofdimethylether synthesis from syngas and their recent progress are reviewed in thearticle. 简要介绍了合成气制二甲醚的原理、工艺流程、双功能催化剂以及近年来的发展状况。
The synthesis, properties, modification and application of polybenzoxazines were reviewed. Besides, the other difunctional benzoxazines and polyfunctional naphthoxazines were also discussed. 综合介绍了苯并嗪树脂的合成、性能、改性和应用,并对其他双酚类苯并嗪和萘并嗪进行了概述。
