Abstract
In this study, research will be carried out to classify the blending behavior of glassy and rubbery polymer in solvent with amines. Commercially preface of a polymer prepared from a new monomer is uncertain and enormously expensive. A strategy to introduce new products into the market without a large investment is to take dissimilar polymers, amines and blend them together to make a new product with unique properties. The blending of polyvinyl acetate, polysulfone and diethanol amine, methyl diethanol amine, mono ethanol amine are examined with dimethyl acetamide solvent, which gives the results of appearance, pH and viscosity values by using measuring device viscometer and general pH testing technique. Through getting these results, the intrinsic miscibility of the mixture was finally established which shows that the homogenous or heterogeneous blends are depending on the blend preparation method and percentage of polymers and amines. The achievement of this advance has been restricted, because the mechanical properties of the blend with amines are classically worse than a simple mixing law would predict.
Highlights
Polymer blending with amines is taken into account as time and cost effective methodology to develop materials with advantageous properties.Polymer Blend is a mixture of two polymers or copolymers
Its means that there is no change occur in pH when the blend is occur PSU and polyvinyl acetate (PVAc). but the viscosity is increases when the PVAc. percentage is increases in PSU due to the pure PVAc. viscosity is greater than the PSU viscosity
It is concluded that PSU, PVAc. and amines blend in all different compositions is miscible in DMAc. solvent
Summary
Polymer blending with amines is taken into account as time and cost effective methodology to develop materials with advantageous properties. Polymer blends are presently more important in scrupulous sectors of polymer industry [1], as they will commonly meet performance requirements that cannot be satisfied by the currently accessible commodity polymers Their attractiveness will increases with the increasing demands for this category of materials. During this research study we prepare the polymer blend of polymeric membrane by the combination of glassy and/or rubbery polymer and adding up the amines. This method ends up in improve the separation ability for CO2/CH4 mixture because polymeric blend membrane using the properties of both glassy and/or rubbery phases with increase the selectivity, permeability, chemical stability and mechanical strength. The overall reaction between CO2 and primary or secondary amines is
