What reactions produce elastomers, thermosets and thermoplastics?
Which are produced by polycondensation, which by polymerization, and which by polyaddition? And most importantly, how is a polyamide produced?
Chemistry?
Hi, I'm really unsure about this worksheet, could someone tell me if it's correct and correct me if something is wrong thanks in advance
How physiologically harmful are these thermoplastics?
Polypropylen Polyethylen polyamide Polycarbonat Acrylonitrile Butadiene Styrene Polymethyl methacrylate Polystyrene Polyoxymethylene I'm interested in plastics and would like to expand my knowledge. Since I work as a molder, or rather, a "process mechanic for plastics and rubber technology specializing in molded parts," my question mainly relates to the thermoplastic form of the plastic. (I wouldn't…
Can anyone help me with chemistry?
Hello everyone 🤓 We had a mock exam today and unfortunately I don't understand anything. I've cut out the questions that I did understand from the picture. Can someone please help me!!!! That would be great
Why do adhesive layers more often have thermoplastic and thermosetting properties?
I read the following in a book: "With the exception of special silicones […], only base monomers capable of forming thermoplastic and thermosetting adhesive layers are used as adhesives." (Habenicht, Kleben 2006) My question is, why? Does it have something to do with the fact that thermoplastics and thermosets are more common? thanks in advance
