Title: Craze-resistant polymodal linear block copolymers with resinous terminal blocks
IPC: C08F297/04
Filed: 1987-03-23
Abstract: Sequential charging of initiator and monomers in a multistage solution polymerization process involving conjugated diene and monovinylaromatic monomers wherein the initial and final charges are monovinylaromatic monomer results in the production of polymodal linear block copolymers with terminal resinous blocks. A typical 6-stage charge sequence is as follows: stage 1: (Si); stage 2: (Si); stage 3: (B); stage 4: (Si); stage 5: (B) and stage 6: (S) wherein (Si) is monovinylaromatic monomer and initiator, (B) is conjugated diene monomer and (S) is monovinylaromatic monomer. At each stage, polymerization is allowed to continue until no free monomer is present. The polymodal block copolymer products comprise high, medium and low molecular weight species designated, respectively, as S1-S2-B1-S3-B2-S4; S2-B1-S3-B2-S4; and S3-B2-S4 wherein S1, S2, S3 and S4 represent, respectively, polyvinylaromatic blocks resulting from polymerization of the first, second, third and fourth charges of monovinylaromatic monomer (stages 1,2,4 and 6); B1 represents a polydiene block resulting from polymerization of the first charge of conjugated diene monomer (stage 3); and B2 represents a polydiene block resulting from polymerization of the second charge of conjugated diene monomer (stage 5). The subject copolymers can be fabricated into sheets and molded objects possessing little color, a high degree of transparency and excellent impact resistance. These fabricated products do not craze on being impacted.
