MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications.
Even though size exclusion chromatography is widely utilized to study natural organic material, there are limitations. One of these limitations include that there is no standard molecular weight marker; [6] thus, there is nothing to compare the results back to. If precise molecular weight is required, other methods should be used.
Food plot in Germany. A food plot is a planted area set aside to act as a supplementary food source for wildlife. The term was coined by the U.S. hunting and outdoor industries and food plots are most commonly planted for game species. Food plot crops generally consist of but are not limited to legumes (clovers, alfalfa, beans, etc.), grains ...
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents.
The homopolymers of acrylate esters (e.g., butyl acrylate) have few applications.Copolymers however have many applications/ They are produced by copolymerization of alkyl acrylates and one or more of the following comonomers methyl methacrylate, styrene, acrylonitrile, vinyl acetate, vinyl chloride, vinylidene chloride, and butadiene.
The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule. [1] [2] [3]For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by ¯ ¯ = ¯, where ¯ is the number-average molecular weight and is the molecular weight of the monomer unit.
Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...
Hydroxyethylmethacrylate (also known as glycol methacrylate) [3] [4] is the organic compound with the chemical formula H2C\dC(CH3)CO2CH2CH2OH. It is a colorless viscous liquid that readily polymerizes. Hydroxyethylmethacrylate is a monomer that is used to make various polymers.
