Linear low-density polyethylene (LLDPE)440-442 is a copolymer of ethylene and a terminal alkene with improved physical properties as compared to LDPE. The practically most important copolymer is made with propylene, but 1-butene, 4-methyl-1-pentene, 1-hexene, and 1-octene are also employed.440 LLDPE is characterized by linear chains without long-chain branches. Short-chain branches result from the terminal alkene comonomer. Copolymer content and distribution as well as branch length introduced permit to control the properties of the copolymer formed. Improvement of certain physical properties (toughness, tensile strength, melt index, elongation characteristics) directly connected to the type of terminal alkene used can be achieved with copolymerization.442... [Pg.771]

The linear addition copolymers of dicyanates are synthesized at equimolecular ratio of the comonomers. If one of the comonomers is used in excess, lower-molecular-weight polymers with corresponding end groups are obtained, which can further react with chain elongation agents. Terminal cyanate groups can be cyclotrimerized to obtain crosslinked polymers. [Pg.46]

The same approach was also used foi OsafCOn in a BBrj solvent 77]. Besides linear and branched hydrocarbons, alkylbromides were also formed. Using BCU ouly hydrocarbons were produced. The mechanism is undemonstrated. Chain elongation could occur by insertion into a M R bond and Lewis acid interaction of the type (30). [Pg.30]
