DEFINITION

Classification: 507/117

Organic component is solid synthetic resin:

(under subclass 103) Composition wherein the organic component is a solid synthetic resin.

(1) Note. A solid synthetic resin for the purpose of this class is a polymer which is described as a solid as such or described in one of the following terms: (1) coagulated (2) elastic (3) elastomeric (4) friable (5) meltable (6) molten (7) powder (8) rubber (9) thermoplastic. A wax is not considered to be a solid even if defined by one or more of the above terms.

(2) Note. In this area, the classification is dependent on the first appearing monomer which is either part of the polymeric backbone or has been reacted subsequent to polymerization, such as a graft or block copolymer.
