The choice of suture materials for surgery is made mainly on the basis of biocompatibility and mechanical properties. The biological interaction with the tissues is considered from the point of view of the inflammatory reaction caused. An ideal suture is one that does not merely avoid negative reactions but also keeps a sterile environment and stimulates the process of healing. An absorbable suture is one which is degraded in body tissues to soluble products and disappears from the implant site, usually within 2 to 6 months. A nonabsorbable suture is resistant to biodegradation, becomes encapsulated in a fibrous sheath, and remains in the tissue as a foreign body unless it is surgically removed (e.g., skin sutures) or extruded. Sutures may be fabricated as monofilaments or multifilaments. The latter are generally braided but sometimes twisted or spun and may be coated with wax, silico...","PeriodicalId":16139,"journal":{"name":"Journal of Macromolecular Science-reviews in Macromolecular Chemistry and Physics","volume":"34 1","pages":"315-324"},"PeriodicalIF":0.0,"publicationDate":"1985-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87143941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such applications include peptide synthesis, phase transfer catalysis, pharmaceutical modification, protein and cell purifications, polymer-bound reagents, and binding assays. Because of the great deal of interest surrounding this subject, this review will describe generally applicable laboratory methods for preparing PEG derivatives from the parent PEG. We have largely restricted discussion to this starting material because most research laboratories interested in applications are not equipped to handle complex ethylene oxide polymerizations used in large-scale industrial preparations and because PEG and some of its ethers and esters are the only commonly available polymeric starting materials. For the purpose of this review, PEG is defined as those polyoxyethylenes having hydroxyl endgroups and a molecular weight of 20,000 daltons or less.","PeriodicalId":16139,"journal":{"name":"Journal of Macromolecular Science-reviews in Macromolecular Chemistry and Physics","volume":"76 1","pages":"325-373"},"PeriodicalIF":0.0,"publicationDate":"1985-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85831051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, the worldwide recession, reduced and varying demand, overcapacity, and fierce price competition has stimulated polyolefin manufacturers to modify their existing facilities, making it feasible to interchangeably manufacture a variety of resins.

The change is known as curing or drying.

These chemical processes connect the many relatively small molecules of the original liquid or paste into a large molecular network or insoluble solid, which may be either rigid or rubbery in consistency depending upon the requirements of a particular application. Among traditional materials, gravure inks and many lacquers dry by solvent evaporation while paints and inks based upon linseed oil “dry” by chemical cross-linking promoted by oxygen in the air.
