Photocomposite materials and adhesive systems are used for direct tooth restoration, among which 5th generation systems are most often used. To ensure curing, they are exposed to the light flux of the dental photopolymerizer, but the requirements and cond... see more

A series of experiments have been carried out and reported. This report describes the stages of the polymerization reaction during emulsion Polyvinyl Acetate (PVAc) synthesis. PVAc was synthesized from the Vinyl Acetate Monomer (VAM) with Ammonium Peroxyd... see more

The objective of this work was to manufacture biodegradable films based on polyvinyl alcohol (PVA) and also to evaluate the effect of the different degrees of hydrolysis (DH) and degrees of polymerization (DP) of PVA on the properties of these films. Four... see more

Poly(N-vinylcaprolactam) (PNVCL) offers superior characteristics as a thermoresponsive polymer for various potential applications. An attractive procedure, namely in-situ polymerization, was used to prepare NVCL/clay nanocomposite in different clay ratios... see more

Indonesia is a major producer of palm oils. However, more than 76% of the production is exported as crude palm oil (CPO) with low economic values. Chemical conversion is necessary to produce more valuable derivatives of renewable biobased material includi... see more

A study on bulk polymerization kinetics of HTPB (Hydroxy Terminated Polybutadiene) and TDI (Toluene Diisocyanate) with infrared (IR) spectroscopy has been conducted. The investigations included the molar ratio of 2,4-TDI to 2,6-TDI isomers, the initial mo... see more

Poly(methyl methacrylate)-b-poly(N-isopropylacrylamide) [PMMA-b-PNIPAM] block copolymers were obtained by a combination of redox polymerization and atom transfer radical polymerization (ATRP) methods in two steps. For this purpose, PMMA macroinitator (ATR... see more

The synthesis of (1)-N-(3,4-dimethoxy-benzyl)-1,10-phenanthrolinium bromide had been conducted from vanillin. Heme polymerization inhibitory activity assay of the synthesized antiplasmodium has also been carried out. The first step of reaction was methyla... see more

Objectives: The polymerization shrinkage of methacrylate-based composites is among the most important causes of failure of composite restorations. The manufacturers claim that bulk-fill composites have a lower polymerization shrinkage than conventional co... see more
