Abstract: Previous studies of tri-n-butylborane-initiated graft copolymerization of methyl methacrylates with hydrated proteinous materials and proteins have focused on the number of grafted-poly (MMA) branches as well as the percent graft and graft efficiency. The number of branches in silk fibroin is 1.3, whereas the number in collagen, gelatin, ovalbumin and wool are 0.1, 0.04, 0.02 and 0.03, respectively. The number of grafted-PMMA branches in synthetic poly-L-peptides is approximately 10-fold less than that in gela… Show more

“…The exothermic reaction was well controlled in the PMMA-TBB material. The present result was consistent with a previous study reporting that the activation energy (Ea) for BPO (15 to 33 kcal/mol) was significantly higher than that for TBB (3.8 to 5.5 kcal/mol) [54]. The experimental conditions, such as measuring temperature in water and using a smaller material volume than the product size, may have caused a lower temperature reading than the actual ones.…”

“…Accordingly, they should be highly active against all such bonds, for example, in natural polymers, proteins and polysaccharides. The production of graft copolymers of natural polymers with synthetic polymers is particularly promising for the production of new materials for medicine, including tissue engineering [23][24][25][26][27][28][29][30][31][32][33][34][35]. Pectin-containing scaffolds are proved to be a successful basis for the reconstitution of cartilage and bone tissue [36][37][38][39][40][41][42][43][44][45].…”

“…Hybrid materials with the inclusion of collagen and polymers of another nature are widely used in medicine [6,7], pharmacy [8], cosmetology [9,10]. To obtain copolymers of collagen and its denaturant gelatin with synthetic monomers, radical initiators of various nature are most often used [11][12][13], including trialkyl boranees [14][15][16]. Grafted copolymers [17] of polymethyl methacrylate and gelatin in aqueous dispersion were synthesized and characterized in the presence of tributyl borane and traces of oxygen.…”
