Why is this entry listed under "heteropolymer"? "Copolymer" is by far the most common term for a polymer with more than one monomer constituent. How do we change the heading to "copolymer"?

Another suggestion. Types of copolymer should be listed first, before the section of block copolymer. If there is no objection, I will change this in a few days.Delmlsfan 22:02, 14 December 2006 (UTC)

Also, should we be using the term "random copolymer." This is an older term, and the preferred name now in polymer science is statistical copolymer, as it is a more correct description. Jeff 16:17, 18 December 2006 (UTC)

This is incorrect. A statistical copolymer and random copolymer are distinct as per IUPAC. See IUPAC "Glossary of Basic Terms in Polymer Science". Pure Appl. Chem. 1996, 68, 2287-2311. (available online here)

Cleanup[edit]

The block copolymer section has a lot of good information but it scans poorly. Needs reworking to be encyclopedic. Will chalk this up for my own project if there are no other volunteers. Irene Ringworm 05:51, 24 February 2007 (UTC)

"Since a copolymer consists of at least two types of constitutional units (not structural units)" - The links redirect me on the same page, about about structural units. But the article says constitutional units and structural units aren´t the same? Greetings from Germany —Preceding unsigned comment added by 217.235.229.64 (talk) 19:02, 2 September 2007 (UTC)

?[edit]

Are you sure it should read monomeric species instead of monomer at the end of the second ssentence? —Preceding unsigned comment added by 75.118.160.109 (talk) 01:21, 14 November 2007 (UTC)

"Crack initiators?"[edit]

Copolymerization is used to modify the properties of man-made plastics to specific needs, for example to reduce crystallinity, modify glass transition temperature or to improve solubility. It is a way of improving mechanical properties, in a technique known as rubber toughening. Elastomeric phases within a rigid matrix act as crack initiators, and so increase the energy absorption when the material is impacted for example. Acrylonitrile butadiene styrene is a common example.

Shouldn't that be "crack inhibitors"? 80.65.195.132 (talk) 10:44, 29 July 2009 (UTC)
