Imide groups were introduced in the hard segment of UV cured polyurethane dispersion (UV-PUD) by extending the NCO terminated prepolymers with pyromellitic dianhydride (PMDA) where the soft segments were prepared from PTMG, H 12 MDI, HDI and DMBA. It was found that imide hard segment, as compared...
High density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP) coupons were immersed for a period of 6 months in Bay of Bengal near Chennai Port (Port) and Fisheries Survey of India (FSI). Samples were retrieved every month and the extent of biofouling and biodegradation...
Enzymatic degradation of poly(3-hydroxybutyrate- co -3-hydroxyalkanoates) (PHBA) biopolyester consisting of 3-hydroxybutyrate (HB) and 15 mol% medium-chain-length 3-hydroxyalkanoates (HA) was studied using a polyhydroxyalkanoates (PHA) depolymerase produced by Ralstonia pickettii T1. It was found...
