Poly(ethylene terephthalate) (PET) is one of the most widely used synthetic polyesters, however, its extensive use creates a long-term environmental burden. Unlike traditional recycling methods, biodegradation i
Safety-enhanced polymer electrolytes based on ABA triblock copolymers were prepared. Segment A is a mesogen-jacketed liquid crystalline polymer with a highTgand stable LC phase, and it serves as physical crosslinking. Seg...
performance parameter The tablets produced by our company can be divided into the following categories: One, PET (polyester) sheet features: is a thermoplastic product, after burning odorless, tasteless, do not produce toxic gas. High transparency, surface without water ripple, no ... Learn More...
Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, ...
PETG, or Polyethylene Terephthalate Glycol, is a thermoplastic polyester that has been chemically modified with the addition of Glycol to limit crystallization and improve toughness. The inclusion of glycol improves PET’s , durability and formability for production. It has a strong impact and abrasion...
(B) a polymer of lactic acid in which the concentration by weight of A with respect to (A+B) is in the range of 30 to 60 % and in which the sum of the fusion entalpy ΔHA and ΔHB of the two polyesters in the mixture is greater than the sum of the fusion entalpies ΔH1...
Derivatives were prepared either by adding heavy-atom reagents to the crystallization drop or by using modi®ed DNA oligonucleotides in crystallization, and diffraction data were collected at 100K±110K using crystals that had been stabilized by addition of 16% propylene glycol before ¯ash-...
An additional 94–147 ms is necessary to generate a helix of dynamin polymer, and thus, at the fastest, 351 ms is required after the neck of endocytic pits becomes ∼36 nm in diameter. Given that Dyn1xA is required at the early stage of the neck constriction when the neck diameter ...
Combination of Imaging FTIR27and an automated polymer identification approach28revealed that MP concentrations in Arctic sea ice are extremely high and therefore sea ice can be seen as a temporary sink for MP. However, even during winter large fractions of the sea ice are exported southward and ...
A polymerisable mesogenic or liquid crystal compound is also shortly referred to as ‘reactive mesogen (RM)’. SUMMARY OF THE INVENTION The present invention relates to compounds of formula I A1and A2are each independently an aliphatic or aromatic carbocyclic or heterocyclic group with up to 20...
