What is molecular weight applied to a polymer?

Polymer molecular weight is the molecular mass of a polymer chain. It can be obtained by multiplying the mass of each repeating unit (M0) by the degree of polymerisation and then adding the mass of end groups. For a linear polymer, it is rare that all polymer chains have the same mass.

Is Perspex a type of plastic?

Poly (methyl methacrylate) (PMMA), also known as acrylic, acrylic glass, perspex, or plexiglass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or …

Is PMMA a homopolymer?

Pure poly(methyl methacrylate) homopolymer is rarely sold as an end product, since it is not optimized for most applications. A small amount of acrylate comonomers are routinely used in PMMA grades destined for heat processing, since this stabilizes the polymer to depolymerization (“unzipping”) during processing.

Which polymer has the highest density?

HDPE is known for its high strength-to-density ratio. The density of HDPE can range from 930 to 970 kg/m3.

Can molecular weight change?

The changes in molecular weight of a long-chain polymer (initially of arbitrary molecular-weight distribution) are studied when the main chain is subjected to random fracture, such as occurs when certain polymers are exposed to high-energy radiation.

What does methyl methacrylate smell like?

Methyl Methacrylate is a colorless liquid with a sharp, fruity odor.

How to calculate the molecular weight of poly methacrylate?

Linear poly(methyl methacrylate) standards of varying molecular weight characterized by GPC were used. The 5.9×104 and 1×104 g mol−1 standards were prepared by catalytic chain transfer polymerization (CCTP) (polydispersity 1.8), and the 9×104 and 3×105 g mol−1 standards were supplied by Sigma Aldrich.

Which is the most common polymer of methacrylates?

General Poly(methacrylates) are polymers of the esters of methacrylic acids. The most commonly used among them is poly(methyl methacrylate) (PMMA). Poly(methyl methacrylate) or poly (methyl 2‐methylpropenoate) is the polymer of methyl methacrylate, with chemical formula C5H8O2)n. It is a clear, colourless poly‐

How is polymethacrylate ( PMMA ) produced in mass?

Poly(methyl methacrylate) is produced by free‐radical polymerization of methyl‐ methacrylate in mass (when it is in sheet form) or suspension polymerization according to the following chart:   Properties Polymethacrylates ‐ 1 PMMA is a linear thermoplastic polymer.

What is the glass transition temperature for poly methacrylate?

Indeed, depending on the alkyl substituent of the ester group, the glass transition temperature (Tg) can be tuned over a very large temperature range (e.g. from −50°C for poly(isooctyl acrylate) up to 190°C for poly(isobornyl methacrylate)).
