Abstract

The thorough characterization of polymer chains grafted through a "grafting-from" process onto substrates based on the determination of number (Mn) and weight (Mw) average molar masses, as well as dispersity (Ɖ), is quite challenging. It requires the cleavage of grafted chains selectively at the polymer-substrate bond without polymer degradation to allow their analysis in solution with steric exclusion chromatography, in particular. The study herein describes a technique for the selective cleavage of PMMA grafted onto titanium substrate (Ti-PMMA) using an anchoring molecule that combines an atom transfer radical polymerization (ATRP) initiator and a UV-cleavable moiety. This technique allows the demonstration of the efficiency of the ATRP of PMMA on titanium substrates and verification that the chains were grown homogeneously.

摘要

基于数均分子量（Mn）、重均分子量（Mw）以及分散度（Ɖ）的测定，对通过“接枝自”过程接枝到基底上的聚合物链进行全面表征颇具挑战性。这尤其需要在不使聚合物降解的情况下，选择性地在聚合物 - 基底键处裂解接枝链，以便能够采用空间排阻色谱法在溶液中对其进行分析。本文的研究描述了一种使用结合了原子转移自由基聚合（ATRP）引发剂和可光解部分的锚定分子，选择性裂解接枝到钛基底上的聚甲基丙烯酸甲酯（Ti - PMMA）的技术。该技术能够证明聚甲基丙烯酸甲酯在钛基底上进行原子转移自由基聚合的效率，并验证链是均匀生长的。
