Copolyamides of nylon‐4,6 and nylon‐4,T [PDF]
Journal of Polymer Science Part A: Polymer Chemistry, 1989 AbstractCopolyamides of nylon‐4,6 and nylon‐4,T were prepared by a two‐step method: (1) a prepolymerization in an autoclave (40 min at 210°C) and (2) a postcondensation in the solid state (4 h, 260°C). On these materials was studied the melting behavior with DSC, the crystalline structure with WAXS, the water absorption, and the mechanical properties ...

Preparation and some properties of nylon-4,2 [PDF]
, 1984 An attempt was made to produce a new short-chain alphatic polyamide nylon-4,2. This polyoxamide can be prepared by polycondensation of tetramethylene diamine and diethyl oxalate.

Hydrogenative Depolymerization of Nylons [PDF]
Journal of the American Chemical Society, 2020 The widespread crisis of plastic pollution demands discovery of new and sustainable approaches to degrade robust plastics such as nylons. Using a green and sustainable approach based on hydrogenation, in the presence of a ruthenium pincer catalyst at 150 °C and 70 bar H2, we report here the first example of hydrogenative depolymerization of ...

Nylon-6/rubber blends: 8. Influence of the molecular weight of the matrix on the impact behaviour [PDF]
, 1994 Blends of nylon-6 with polybutadiene were prepared with comparable morphology and different molecular weights of the matrix. These specimens were tested using the notched Izod impact test and the notched tensile impact test.

Angewandte Chemie, EarlyView.Mechanosynthesis of polyZIF overcomes MOF‐polymer phase incompatibility via in‐situ polymer‐Zn2+‐Im coordination networks. Pore architecture engineering yielded molecular‐sieving membrane transport channels that enhanced butadiene permeance to 332 GPU while maintaining outstanding selectivities against C4 hydrocarbons through the size‐exclusion ...

Journal of General Microbiology, 1954 SUMMARY: A tissue grinder is described, consisting of a nylon pestle mounted on a stainless steel shaft and revolving within a Pyrex tube; a screw is cut in the pestle to increase its efficiency. The whole device is sealed with a Subaseal bung and may be sterilized by autoclaving. Optimum grinding with minimum heating is produced by rotating the pestle
