Thermoplastic reactive

2-PBD can be applied to films auid tubes in thermoplastics field. In rubber field, cross-linking foam like EVA is a possibility. In coatings, photo-curing paint is a possibility. 

ACS Symposium Series American Chemical Society Washington, DC, 1974. 

In the adhesion field, hot-melt type adhesive is a possibility. 

In the fiber field, graphite fiber is a possibility. In other fields, photo-sensitive polymer is a possibility. 

We will describe the following some of possible applications of the 1, 2-PBD that are useful from an industrial view point.

PROPERTIES OF SPECIAL INTEREST Syndiotactic 1,2-polybutadiene is a reactive thermoplastic resin, which has characteristics of both a thermoplastic and an elastomer. 

Research to develop jute and kenaf fiber thermoplastic alloys is based on first thermoplasti-cizing the fiber matrix as described above, followed by grafting of the modified fiber with a reactive thermoplastic. This type of composite has the thermoplastic bonded onto the jute or kenaf so there is only one continuous phase in the molecule. This is done in one of two ways. In one case, the matrix is reacted with maleic anhydride that results in a double bond in the grafted reacted molecule. This can then be used in vinyl-type additions or in free radical polymerization to either build a thermoplastic polymer or graft one onto the jute or kenaf backbone. In the second method, the matrix is reacted with a bonded chemical and then reacted with a low-molecular-weight thermoplastic that has been grafted with side-chain anhydride groups. 

JSR). The 1, 2-PBD is a low crystalline polymer (15-259 crystallinity) and a unique thermoplastic having property between plastic and rubber. On the other hand, the 1, 2-PBD is regarded as a novel functional polymer, namely, as a reactive thermoplastic. 

Reactive Melt Polymerization. The liqiud composite molding (LCM) method is established for the fabrication of thermosets. In contrast, reactive thermoplastic LCM processes are developed for only a few engineering polymers. The technique was applied to low melting PA 6T/6I oligomers [39]. 

The adhesion of a flexible polymer to a mineral surface through a silane-modified resinous or tacky phase differs from the use of resinous cross-linkers for reactive thermoplastics in that only the polymer at the interface is modified to obtain adhesion without changing the properties of the film itself. 

Viscosity of reactive and non-reactive thermoplastic matrix materials. (From reference 17.)... 

Like the pultrusion process, the selection of a suitable thermoplastic matrix material mainly depends on the desired mechanical properties and the desired long-term service temperature. The range of usable matrix materials starts with standard polymers such as polyethylene (PE) or polypropylene (PP) and ends with high performance polymers such as polyetherimide (PEI) or poyletheretherketone (PEEK). Recent developments have shown that the processing of reactive thermoplastic materials is possible as well (CBT). For some physical properties of common matrix materials see Table 8.2. °... 

The use of conventional organofiinctional silanes, as described in the section on filled thermosetting resins, has been tried in filled thermoplastic resins with mixed results. Oren-ski and co-workers reported good results with the use of Union Carbide A-187 and A-1100 in wollastonite filled engineering resins at high filler loading. Attempts to extend this approach to less reactive thermoplastic resins, such as polyolefins, were less successful.
