“…For the macromolecular synthesis of the vast majority of well-de ned polymers, reversible addition-fragmentation chain transfer polymerization technique (RAFT) is one of the most widely used C/LRP methods. Because of the method's compatibility with a variety of monomers and reaction circumstances, it is regarded as being exible [14][15][16][17][18][19][20][21]. Additionally, research on the bioactivity properties of nylon-3 (poly-β-alanine) copolymers and derivatives has grown.…”

Synthesis and characterization of poly(β-alanine-b-vinyl benzyl-g-vinyl chloride) [poly(BA-b-VB-g-VC)] block-graft copolymer was done by reversible addition-fragmentation chain transfer polymerization and 'click' chemistry. For this, poly-β-alanine with a vinyl end group was synthesized by hydrogen transfer polymerization of acrylamide. Bromine-terminated poly-β-alanine (PBA-Br) was obtained by treating the synthesized poly-β-alanine with hydrogen bromide. Poly-β-alanine ethyl xanthate (macro-RAFT agent) was synthesized using PBA-Br and potassium ethyl xanthate. Poly(β-alanine-b-vinyl benzyl chloride) [poly(BA-b-VBC)] block copolymer was obtained by reversible addition-fragmentation chain transfer polymerization of macro-RAFT agent with vinyl benzyl chloride. Azido-terminated poly(β-alanine-b-vinyl benzyl chloride) [poly(BA-b-VBC)-N 3 ] was synthesized by the reaction of poly(BA-b-VBC) with sodium azide. Alkyne-terminated polyvinyl chloride (PVC-propargyl) was obtained by treating polyvinyl chloride with propargyl alcohol. Finally, the synthesis of poly(BA-b-VB-g-VC) block-graft copolymer was carried out by the 'click' chemistry method of poly(BA-b-VBC)-N 3 and PVC-propargyl. The products were characterized by various spectroscopic and thermal methods.

“…Bu makro moleküllerin sentezi için tersinir katılmalı/ayrışmalı zincir transfer (RAFT) polimerizasyonu en son geliştirilen kontrollü radikal polimerizasyon yöntemini temsil eder ve çok iyi tanımlanmış çeşitli polimerlerin sentezi için güçlü bir tekniktir [15]. Kontrollü radikal polimerizasyonların genel avantajları olan polimer mimarisinin ve molekül ağırlığının önceden ayarlanabilmesi ile düşük molekül ağırlığı dağılımına (dispersiteye) sahip polimerlerin üretimi RAFT'ın da önemli avantajları arasındadır [16][17][18][19][20][21][22][23][24][25][26]. Termoplastik özellik gösteren polistiren, birçok metale göre üretiminin oldukça ucuz ve diğer malzemelere iyi bir alternatif olması, sahip olduğu özelliklerin geliştirilerek yeni özellikler kazandırılması ihtiyacını gerektirmiştir [27].…”

ÖzPoli (4-vinilbenzil-g-stiren) [poli(VB-g-S)] aşı kopolimeri tersinir katılmalı/ayrışmalı zincir transfer (RAFT) ve serbest radikal polimerizasyon (SRP) teknikleri kullanılarak sentez edildi. Bu amaç için, 4-vinilbenzil klorür monomeri kullanılarak SRP yöntemiyle poli(4-vinilbenzil klorür) [poli-4-VBC] polimeri sentezlendi. İkinci aşamada, poli-4-VBC polimeri ile potasyum etil ksantat reaksiyona sokularak makro-RAFT ajanı oluşturuldu. Son aşamada, RAFT tekniğiyle makro-RAFT ajanı varlığında stiren monomeriyle poli(VB-g-S) aşı kopolimeri sentez edildi. Sentezlenen ürünler 1 H-NMR, FT-IR, TGA, SEM ve Dinamik Işık Saçılımı (DLS) cihazları gibi spektroskopik ve termal analiz teknikleri kullanılarak karakterize edildi.Anahtar kelimeler: Aşı kopolimer, 4-vinilbenzil klorür, stiren, makro-RAFT ajanı, serbest radikal polimerizasyonu, tersinir katılmalı/ayrışmalı zincir transfer polimerizasyonu.

A light stabilizer compound of 2‐(2′‐propionyloxy‐5′‐methylphenyl) benzotriazole (AMB) was synthesized by the esterification of the 2‐(2′‐hydroxy‐5′‐methylphenyl) benzotriazole with acryloyl chloride (AC), and the AMB was then copolymerized with the methyl methacrylate (MMA), butyl acrylate (BA), and silicone monomers (D4) to prepare the silicone light toughener of poly(D4‐MMA‐BA‐AMB). Effects of the AMB monomer on the conversion and polymerization stability and the toughening and photostabilizing effects of the poly(D4‐MMA‐BA‐AMB) on the polycarbonate (PC) were studied. The prepared multifunctional toughening agent was characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, thermogravimetric analyzer, transmission electron microscopy, dynamic light scattering analyzer, and ultraviolet absorption spectroscopy. Results show that the prepared poly(D4‐MMA‐BA‐AMB) toughening agent possessed core–shell structure and could effectively absorb the ultraviolet rays. Although the addition of the poly(D4‐MMA‐BA‐AMB) toughening agent had a negative effect on the tensile strength of the PC, it could greatly improve the low‐temperature notched impact strength, toughness performance, and yellowness performance of PC products after UV irradiation. Compared with the silicone toughening agent, the toughening agent of the poly(D4‐MMA‐BA‐AMB) had better anti‐ultraviolet property for the PC/poly(D4‐MMA‐BA‐AMB) composite. © 2019 Wiley Periodicals, Inc.
