An improved procedure and apparatus for introducing liquids within a thermoplastic or thermoset production system are provided. Such an inventive apparatus comprises a storage tank for the desired liquid, a device which connects to a flow channel (such as a manifold or pipe) through which the target thermoplastic or thermoset composition is flowing, and a transfer line connecting the storage tank with the connecting device. The connecting device itself easily attaches and detaches to the flow channel through a spring-loaded or sliding-lock mechanism. Such a novel apparatus permits an ease in changeover from one liquid to another without the need for time-consuming cleaning and without complicated shut-off, removal, and replacement steps. Furthermore, such an apparatus allows for quick start-up, a drastic reduction in time required for changeover, and, with the connecting device being attached directly to the flow channel, a reduction in potential clogging through the unwanted misdirection of thermoplastic or thermoset composition into the connecting device and/or transfer line itself. As noted above, the particular procedure for producing such thermoplastic or thermoset compositions through utilization of such an apparatus is encompassed within this invention as well.
