poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

In the main search, efforts are made to develop properties of PMMA resin that is used: To create a blend polymer for upper and lower prosthesis complete denture, several weight ratios poly vinyl pyrrolidone (pvp) (0,2%, 6%, 10%, 14%, 18%, 22%, 26%) were added cold-cured methyl methacrylate (PMMA). The effects external polyvinylpyrrolidone (PVP) concentrations on mechanical features such as hard...

Radiation induced grafting of acrylic acid (AA) and binary mixture of acrylic acid/N-vinyl pyrrolidone (NVP) has been carried out on poly(ethylene terephthalate) (PET) fabric. The grafted fabrics are immobilized with collagen via carbodiimide coupling to make the fabric bioreceptive and biocompatible for cell seeding and grafts. Atomic force microscopy and scanning electron microscopy observati...
