Xanthate-derived mercaptophosphonates for thiol-ene modification of styrene-butadiene rubber
نویسندگان
چکیده
The functionalization of elastomers by phosphonate groups remains relatively unexplored considering the great potential these polymers would represent for applications. In this paper, thiol-functional oligophosphonates were designed and coupled a thiol-ene reaction to styrene-butadiene rubber (SBR). We adopted RAFT methodology with dimethyl vinylphosphonate (DMVP) high-temperature thermolysable xanthate, afford monophosphonate DMVP-SH P(DMVP)5-SH, mercapto(oligophosphonate) DPn = 5. conducted comparative study coupling P(DMVP)5-SH SBR different degrees functionalization. observed that was as reactive DMVP-SH. Although only limited grafting could be achieved without alteration structure radical intercoupling reactions, found superior increasing content thanks its oligophosphonate character.

Rapid Modular Synthesis and Processing of Thiol−Ene Functionalized Styrene−Butadiene Block Copolymers
Diblock and triblock copolymers of poly(styrene)-block-poly(1,2-butadiene) (PS/PB) and PS/PB/PS were modified by photochemical thiol−ene chemistry to process selected functional nanopatterned polymers, with reaction completion in 1 h. PB molecular weight (MW) and thiol−ene ratios were systematically varied based on a model monomer, boc-cysteamine, to determine the efficiency of the reaction. Th...

A review of the literature and an update that is in progress of a previous retrospective cohort mortality study of the styrene-1,3-butadiene industry are discussed. The follow-up has now been extended from April 1, 1976, through December 31, 1981, for plant B and December 31, 1982, for plant A. The person-years at risk of death have gone from 34,187 to 43,341 in plant A and from 19,742 to 26,31...
متن کاملThe Rheological Behavior of Wheat Starch Particulates Filled Uncured Styrene-Butadiene Rubber
This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...

The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...
