The Non-local Photo-Polymerization Driven Diffusion (NPDD) model was introduced to describe the observed drop-off in the material's response for higher exposing spatial frequencies. Recent work carried out on the modeling of the mechanisms which occur in photopolymers during-and post-exposure, has led to the development of a tool, which can be used to predict the behaviour of these materials under a wide range of conditions. In this article, based on the chemical reactions of chain transfer agents, we explore this extended NPDD model, illustrating some of the useful trends, which the model predicts and we analyse their implications on the improvement of photopolymer material performance.

“…Thiols and sulphides perform important biological functions, especially in life processes. There are also known other applications of thiols, e.g., as chain transfer agents in the synthesis of polymers used for optical devices [1][2][3][4].…”

“…Thiols play a significant role among the chain transfer agents because of their efficiency in obtaining polymers of the desired molecular mass. Two important parameters that determine such use of thiols are weakness of the S-H bond and high reactivity of the thiol radicals [4][5][6]. The weakness of the S-H bond can be explained by the high reactivity of these compounds towards chain-carrying macroradicals, leading to high chain transfer constants, irrespectively of the used monomer.…”

The paper presents the synthesis, structure and polymerization of S-phenyl 2-methylprop-2-enethioate (PSM). This compound was prepared in the reaction of thiophenol with methacryloyl chloride. The obtained PSM was purified on the chromatographic column. Chemical structure of the monomer was confirmed by spectroscopic methods (ATR-FTIR, GC-MS, 1 H and 13 C NMR). Next bulk polymerization of PSM with styrene (St) or methyl methacrylate (MMA) was performed. In this way, linear copolymers were obtained. The number and mass average molar mass of the obtained copolymers were determined by gel permeation chromatography (GPC). Additionally, crosslinked copolymers of the commercial monomer S,S 0 -thiodi-4,1-phenylene bis(thiomethacrylate) (DMSPS) under the same conditions were synthesized. The influence of thiol monomers on the physico-chemical properties of the obtained copolymers was determined. Thermal properties of the synthesized materials were investigated by means of DSC and TG/DTG.
