摘要

Abstract

" Thiol-yne” click reaction has already been widely applied in synthesis and modification of new polymer structures or novel materials due to its specific features. However

in most studies

only chain-end strategy was employed when using the di-addition feature of thiol-yne reaction

thus the in-chain di-addition strategy could endow us with a broader space to develop the synthesis of advanced polymers. Therefore

in this paper

the features of in-chain mono- and di-addition were investigated when modifying the alkyne-functionalized polymers to prepare grafted polymers

via

thiol-yne click reaction. The results showed that it is almost impossible to obtain the in-chain di-adducts even under excess feeding of chain-end thiol-functionalized grafts

while only the in-chain mono-adducts could be obtained efficiently. Further researches investigated that the controlled grafting could be encountered when carrying out the thiol-yne click reaction between chain-end alkyne-functionalized polystyrenes and chain-end thiol-functionalized polystyrenes under proper feedings. Therefore

the effect of steric-hindrance might be the primary reason for the alternative grafting

via

thiol-yne click reaction between in-chain and chain-end alkyne-functionalized polymers.
