WebAs a promising new dyeing process without using water, the non-aqueous medium dyeing of polyester has attracted people’s attention and some progress has been made in related research. However, the oligomers of polyester fiber can affect the dyeing of polyester during the use of a silicone waterless dyeing system. Based on this point, the oligomer problem … WebPolylactide. Polylactic acid (PLA) is biodegradable hydrolyzable aliphatic semicrystalline polyester produced through the direct condensation reaction of its monomer, lactic acid, as the oligomer, and followed by a ring-opening polymerization of the cyclic lactide dimer.

Oligomers are built from the same monomer units as … WebPolymer 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. There is always a distribution existed. black noir in the boys

In chemistry and biochemistry, an oligomer is a molecule that consists of a few repeating units which could be derived, actually or conceptually, from smaller molecules, monomers. The name is composed of Greek elements oligo-, "a few" and -mer, "parts". An adjective form is oligomeric.

Here we define a critical parameter q which is the maximum number of ester bonds in an oligomer chain. q is an empirical parameter that can be decided by experiments. If the number of ester bonds in a polymer chain is larger than q, it is defined as a long polymer chain gardener crouch end
