How is PLA made and what are the key steps involved in the production process?
Polylactic acid (PLA) is made through a process called polymerization, where lactic acid molecules are linked together to form long chains. The key steps in the production process of PLA include fermentation of corn or sugarcane to produce lactic acid, purification of lactic acid, polymerization of lactic acid into PLA, and finally processing the PLA into various products such as packaging materials, textiles, and 3D printing filaments.
Does PLA dissolve in acetone?
Yes, PLA (polylactic acid) dissolves in acetone.
What chemical reaction formed these large molecules?
Large organic molecules (macromolecules) are generally formed by condensation reactions between smaller molecules.Condensation means that a small molecule is formed from the atoms removed during the reaction. In cells, the small molecule is water, so the type of condensation reaction is dehydration.Examples:glucose + (chain of n glucose residues) forms chain of n + 1 residues + wateramino acid + (chain of n amino acid residues) forms chain of n + 1 residues + water
What is concentration polymerization?
If you're talking about condensation polymerization, it is a reaction in which monomers join together to give a long chain molecule (the polymer) and a small molecule, usually water or hydrochloric acid, like Nylon.
What is the condensation polymerization reaction between 2 amino acids to form a peptide bond?
Condensation polymerization between two amino acids involves the removal of a water molecule to form a peptide bond. One amino acid donates an amine group (-NH2) while the other donates a carboxyl group (-COOH), forming a peptide bond (-CO-NH-). This reaction occurs through a nucleophilic acyl substitution reaction.
What is dextron?
It is a copolymer of polyglycolic acid and polylactic acid
What are the similarities between addition polymerization and condensation polymerization?
Polymerization describes the formation of of large molecules (polymers) with repeating structure from smaller molecules (monomers) . The word polymer comes from Greek words meaning many (poly-) and parts (-mer). Many of the resulting molecules are plastics, so polymer is occasionally used in place of the word plastic, though this is not an accurate usage. Polymerization is an all-encompassing term that describes formation of polymers by any method.There are two main types of polymerization; addition polymerization and condensation polymerization. Addition polymerization creates larger molecules by opening up double bonds on the smaller molecules (monomers). These opened-up bonds react with parts of other monomers (single part) to form dimers (double part). This reaction can repeat to add another molecule to for a trimer (three part). This continues until you obtain the right size molecule and you stop the reaction. Addition polymerixation can occur using a single type of monomer. There are no by products of the reaction except the longer chain molecules (polymers).In condensation polymerization, two monomers of different types are used. They have different types of reactive (or functional) groups on them. A reaction between monomer A and monomer B results in a dimer, plus another small molecule (often water) that is not part of the polymer. To create long polymers the monomers must have reactive groups on both ends or a chain cannot be formed.Polymerization is an all-encompassing term for creating polymers by any method. Condensation Polymerization is a term denoting a specific type of reaction for creating polymers.
Is Dacron an Addition polymer?
Yes, Dacron is an addition polymer. It is a synthetic polymer produced through the addition polymerization of ethylene glycol and terephthalic acid. This process creates long chains of repeating units, known as polymers, which are characteristic of addition polymerization.

What is the new sun chip bags made out of?
PLA, PLA stands for polylactic acid, or polylactide, a versatile polymer made from plants.
What are stitches made from?
It depends whether it is absorbable or non-absorbable. Absorbable ones are made from polyglycolic acid, polylactic acid, and polydioxanone. However the non-absorbable ones are made from polypropylene.
What is advantage of polylactic acid?
Polylactic acid (PLA) is biodegradable and derived from renewable resources such as corn starch or sugar cane. It has a lower carbon footprint compared to traditional plastics, making it more environmentally friendly. Additionally, PLA is versatile and can be used for a variety of applications including packaging, 3D printing, and medical implants.
